== Glass Print Plate Usage ==
Glass plate is of GO-3D brand, hopefully real mccoy stuff that is flat... It is covered with a PEI sheet that is adhered to the plate with 3M 468MP High Temp Tape. A blue silicone heat transfer sheet keeps the glass in place with friction and fills gaps between the plate and the aluminum bed, it is a type of silicone used for heat sinks for electronics.
 
* NEVER CLAMP glass plate to bed. It will cause warping of the glass plate. Yes glass warps and bends, look it up. The silicone sheet will keep it in place no problem.
*One corner of the print plate is marked 'Front Right' and is blacked in a little around the corner. When facing the printer, this corner goes to corner that is on the right-hand side and is closest to you (duh, but just to be sure...).
*The temperature of the surface of the glass plate will be lower than the aluminum bed, may have to use higher bed temp than on other printers
* PEI sheet is prep-free surface for ABS and PLA, hot or cold. If you have another material, check first to make sure it will work on PEI. If not, then put tape on top of the sheet and then glue/hairspray/whatever.
* Clean PEI sheet with 85% Isopropyl Alcohol and a paper towel, a green spray bottle should be near the printer. Can also use soap and water.
* The flat spatula used to remove objects from the print plate is also useful for removing glass plate from silicone sheet.

Use Cubic Infill (Available only in Slic3r prusa edition), as it provides rigidity in all directions [[Prusa Cubic Infill]]and doesn't make printer resonate.
See https://github.com/prusa3d/Slic3r-settings


Do not use honeycomb -- as at the speeds of the default settings, it will cause printer to resonate and skip.
==A few random printing tips==


PLA:
*Smaller prints will better adhere to the bed than larger prints. If the print hasn't failed in the first 10% of the print job, it will be unlikely to fail after that.


In Slic3r in Fillament Settings tab, '''Right Extruder''' filament profile and in Print Settings tab, '''Fast''' print profile.
*Use Cubic Infill (Available only in Slic3r prusa edition), as it provides rigidity in all directions [http://www.prusaprinters.org/introducing-slic3r-prusa-edition/] and doesn't make printer resonate.


First Layer:
*Do not use honeycomb -- as at the speeds of the default settings, it will cause printer to resonate and skip.
  Filament: 220
  Bed:      70


*Leaning or drifting prints? Tighten all the belts, especially the Y-axis stepper motor belt. That stepper is prone to becoming loose because the Y-stepper motor puts out more power than the X. A link to a video is in the maintenance section.


Other Layers:
*Always store the printer with the X carriage in a corner. (It homes itself to the back left corner anyway when a print is done). But this is to prevent the X and Y axis rods from sagging over time, especially the X axis. It's a known problem, I think, I swear I read it on the internet!
  Filament: 210
  Bed:      60
 
ABS:
 
In Slic3r in Fillament Settings tab, '''ABS Right''' filament profile and in Print Settings tab, '''ABS_first_layer''' print profile.
 
 
For abs you '''absolutely have to''' have a heated chamber, or ABS prints not stick to kapton tape no matter what.
In order to construct heated chamber -- cover the front of printer with a piece of plywood or MDF from the workshop and put some cardboard on top of the printer out of extruder path so the heat escapes more slowly. Pre-heating heaated bed for 5 minutes before starting helps a lot -- set the Bed temperature to 100C in Octopi temperature tab.
 
It's better to start ABS prints towards the back of the printer where ambient temperature is more stable. To disable auto-centering, in Slic3r Prusa Edition go to File --> Preferences then uncheck 'Auto-center Parts'.
 
First Layer:
    Fillament: 240
    Bed:      100
 
Other Layers:
    Fillament: 235
    Bed:      95

| Y-axis appeared to be skipping steps, but we found that there was a set screw loose on the timing pulley on one of the sides, so the whole gantry was driven by the belt on one side only. We tightened the set screw and squared the axis. Also, we flipped the timing belt pulley (hub toward the motor) on the Y axis motor so that the belt doesn't touch the motor flange. It's harder to access but it's tightened well and hopefully you won't have to tighten it again. We also retightened all the other belts for good measure. It works well now.

| The feeding tube for the filament is too wide (4 mm ID 6 mm OD) and too stiff as a result. The problem is, it pushes on the print head in one direction so when the axis is loose, it is printing skewed towers of pisa, in the direction in which the tube pushes. We fed the wire without the tube so that there is no extra pressure on the axis. Therefore the printing errors average to zero.
We bought a smaller and less springy tube (also PTFE) but we are waiting for someone more knowledgeable to install it.

| Loosened the Y-axis short belt, lol. In my zeal I tightened it too much, I guess... (the prints were still drifting back a little, the vertical lines were wobbly...) The belt is good now I think, it should make a low sound when you strum the belt. Also changed the screws holding the Y-stepper, added washer and a rubber ring to keep it in place.

| Tightened X belt, and the small Y belt that connects the motor to the cross rod. Cleaned and lubricated all rods (X, Y, Z). Lubricated Z lead screw. Lubricated the rod bearings on the X and Y (including that the bearings for the cross rod that connects to two Y long belts). Tightened the coupling on the Y axis stepper motor.
Prints were drifting (aka. leaning) towards the rear of the printer and it was driving me nuts. Turns out this can be due to a loose belt. The replicator and clones are susceptible the Y axis becoming loose because extra torque is outputted by the motor since it has to move the extruder carriage and the X stepper.
I also removed some cobwebs from under the printer electronics.
| Rana

| Nov-Dec, 2018
| The aluminum print bed is warped (bowed, with middle as the high point). After trying to level it five million times, finally hit the printer with a baseball bat and it fixed it. Just kidding. Bought a GO 3D glass plate for the bed and a PEI sheet and a silicone heat transfer mat that keeps it in place.

Features

Background information on printer and review of it -- http://www.best3dprinterguide.com/flashforge-creator-x-review-dual-extruder-3d-printer/

  • FlashForge Creator Pro
  • 225 x 145 x 150 mm print volume
  • Dual extruder
  • 1.75mm filament
  • Nozzle max temp: 250 C
  • Heated bed max temp: 120 C
  • Removable glass print plate with PEI sheet. Silicone heat transfer sheet to hold it. The stock aluminum build plate (covered in a black substance) is bowed with the middle as the high point.

Glass Print Plate Usage

Glass plate is of GO-3D brand, hopefully real mccoy stuff that is flat... It is covered with a PEI sheet that is adhered to the plate with 3M 468MP High Temp Tape. A blue silicone heat transfer sheet keeps the glass in place with friction and fills gaps between the plate and the aluminum bed, it is a type of silicone used for heat sinks for electronics.

  • NEVER CLAMP glass plate to bed. It will cause warping of the glass plate. Yes glass warps and bends, look it up. The silicone sheet will keep it in place no problem.
  • One corner of the print plate is marked 'Front Right' and is blacked in a little around the corner. When facing the printer, this corner goes to corner that is on the right-hand side and is closest to you (duh, but just to be sure...).
  • The temperature of the surface of the glass plate will be lower than the aluminum bed, may have to use higher bed temp than on other printers
  • PEI sheet is prep-free surface for ABS and PLA, hot or cold. If you have another material, check first to make sure it will work on PEI. If not, then put tape on top of the sheet and then glue/hairspray/whatever.
  • Clean PEI sheet with 85% Isopropyl Alcohol and a paper towel, a green spray bottle should be near the printer. Can also use soap and water.
  • The flat spatula used to remove objects from the print plate is also useful for removing glass plate from silicone sheet.

Usage

UPDATE: See the "Cura 3 Settings for this Printer" section for how to configure Cura 3.4.1 to use this printer.

Creator Pro uses different toolchain than the rest of the printers in the lab. This printer is based on one of Makerbot printers and Makerbot as a company would rather have you use Windows-only makerbod-approved software.

However, it is possible, to use the printer with open source toolchain based on Slic3r. Slic3r Prusa Edition is highly recommended.

Use Instructions in the log from Jan 2020 at the top of this wiki.

It is still possible to use makerbot software, just generate an .x3g file instead of .gcode and upload it to octoprint.

It is still possible to use cura, just edit and save your models with STL, then load them into Slic3r and print

SD Card

You can print from the printer directly by putting your print file on an SD card, there is one already in the printer. It only accepts x3g files, so you will have to convert your .gcode file to x3g using this utility called GpxUi http://markwal.github.io/GpxUi/

A copy of GpxUi can be found on the SD card in the printer.

  • Smaller prints will better adhere to the bed than larger prints. If the print hasn't failed in the first 10% of the print job, it will be unlikely to fail after that.
  • Use Cubic Infill (Available only in Slic3r prusa edition), as it provides rigidity in all directions [1] and doesn't make printer resonate.
  • Do not use honeycomb -- as at the speeds of the default settings, it will cause printer to resonate and skip.
  • Leaning or drifting prints? Tighten all the belts, especially the Y-axis stepper motor belt. That stepper is prone to becoming loose because the Y-stepper motor puts out more power than the X. A link to a video is in the maintenance section.
  • Always store the printer with the X carriage in a corner. (It homes itself to the back left corner anyway when a print is done). But this is to prevent the X and Y axis rods from sagging over time, especially the X axis. It's a known problem, I think, I swear I read it on the internet!

June 12, 2019 Y-axis appeared to be skipping steps, but we found that there was a set screw loose on the timing pulley on one of the sides, so the whole gantry was driven by the belt on one side only. We tightened the set screw and squared the axis. Also, we flipped the timing belt pulley (hub toward the motor) on the Y axis motor so that the belt doesn't touch the motor flange. It's harder to access but it's tightened well and hopefully you won't have to tighten it again. We also retightened all the other belts for good measure. It works well now. Misha
May 2019 The feeding tube for the filament is too wide (4 mm ID 6 mm OD) and too stiff as a result. The problem is, it pushes on the print head in one direction so when the axis is loose, it is printing skewed towers of pisa, in the direction in which the tube pushes. We fed the wire without the tube so that there is no extra pressure on the axis. Therefore the printing errors average to zero.

We bought a smaller and less springy tube (also PTFE) but we are waiting for someone more knowledgeable to install it.

Jan 16, 2019 Loosened the Y-axis short belt, lol. In my zeal I tightened it too much, I guess... (the prints were still drifting back a little, the vertical lines were wobbly...) The belt is good now I think, it should make a low sound when you strum the belt. Also changed the screws holding the Y-stepper, added washer and a rubber ring to keep it in place. Rana
Jan 11, 2019 Tightened X belt, and the small Y belt that connects the motor to the cross rod. Cleaned and lubricated all rods (X, Y, Z). Lubricated Z lead screw. Lubricated the rod bearings on the X and Y (including that the bearings for the cross rod that connects to two Y long belts). Tightened the coupling on the Y axis stepper motor.

Prints were drifting (aka. leaning) towards the rear of the printer and it was driving me nuts. Turns out this can be due to a loose belt. The replicator and clones are susceptible the Y axis becoming loose because extra torque is outputted by the motor since it has to move the extruder carriage and the X stepper. I also removed some cobwebs from under the printer electronics.

Nov-Dec, 2018 The aluminum print bed is warped (bowed, with middle as the high point). After trying to level it five million times, finally hit the printer with a baseball bat and it fixed it. Just kidding. Bought a GO 3D glass plate for the bed and a PEI sheet and a silicone heat transfer mat that keeps it in place. Rana
Aug 8, 2018 Added Lokbuild surface to print bed. No more tape! see section above for usage info Rana
Jun 13, 2018 When trying to unload the PLA in the right head -- via the Utilities menu -- the Black PLA would not come out. So eventually just cut that filament (with about 6 inches extra left), to be able to finish working on the Type A printer. Allen
Jun 6, 2017 Applied new layer of kapton tape, replaced right fan which had a broken blade. The fan is 24V Alex V.
May 17, 2017 Pi configured with static IP in /etc/dhcpcd.conf.

Nozzles aligned vertically, successfully printed PLA with PVA support: 210°C for both extruders, bed off, blue tape.

May 2, 2017 Left side of the bed was way higher than the right side. This caused some damage to kapton tape. Re-aligned by eye. Alex V.
Apr 27, 2017 Printed something that was ~90% as long as the short side of the bed (y-axis in slic3r). Had to level the bed a little bit, but it printed fine. I used ABS juice to get it to stick (and blocked the build volume with cardboard) Rana
Feb 18, 2017 Myles mentioned about unlevelled printing bed. I leveled the bed properly, however I printed a small model in the middle of the table. Everything works fine. If you will print a large model may be you will need additional tuning. Mike P.
Feb 9, 2017 Replaced the original print head plate with 3D printed model to reduce strain on wires going to print head. Added 3D printed extruder cable support. The original print head plate in my members' box. Alex V.
Jan 31, 2017 Corrected wire order on right drive motor, both motors feed filament correctly now. Nozzles need to be vertically aligned, one is lower than the other and scrapes the previous layers. Adam
Jan 26, 2017 Replaced Fillament with Orange Monoprice. Cleaned nozzles, drive gears. Right gear doesn't pull fillament properly. Either gear or nozzle needs to be replaced. Alex V, Myles, Mike P
Dec 29, 2016 Bed level adjusted. Heated bed support needs to be disassembled and left front (my left) leveling assembly needs to be readjusted Alex V.
Nov 29, 2016 Right Extruder cleaned, Left Extruder should be clean too Rana
