Usage and Slicer

• there is no octoprint or other network connection set up yet. There is usb port on the side of the touchscreen and there should be a usb stick in it, use that
• see next section for configs for PrusaSlicer
  • to import into prusa slicer: File -> Import -> Import Config Bundle
    • to get the physical printer profile make sure to do the bundle on not just "import config"!!!
  • on the left panel of prusa slicer, at the top of that panel there should be 3 drop down menus: "Print settings", "Filament" and "Printer". In those menu's select the profiles for the Ender 5 Plus
    • BE SURE that in the printer profile is set to the ender 5 plus, or else their will be wrong PHYSICAL (REAL LIFE) machine movement limits and the gcode that is generated will move the printer all weird and could damage the printer!!
  • adjust the print settings (add support, or a brim or more perimeters, etc) if desired
  • slice it and export the gcode to the usb stick, then plug that into the side of the screen

• to load the filament push it all the way through the tubing to the direct drive extruder, then can use the knob on the extruder to load it down to the nozzle. If you have trouble inserting it into the long tube, try to rotate the filament while pushing, if all else fail then push down on the blue collar around the fitting to remove the tubing from it and can push the filament through

• always check the first layer!!! there is live z-adjust on the touchscreen called "baby steps"

Tips for printing with a big nozzle

• The whole point of the big nozzle is to have thicker extrusion lines and bigger layer heights, so less extrusion lines in total are drawn by the printer
• a 0.4mm nozzle will take five extrusion lines to draw 2mm of perimeter, whereas the 1mm nozzle can do it in two lines. 2mm perimeters are pretty freaking strong, you can get away with like infill at 10% or 15% (some people do 5% lol) because most of the strength comes from the perimeters. Just set the top and solid infill to 5 or more layers to make sure it covers up any drooping of the top layers
• So a 1 mm nozzle has a max layer height of 0.75mm, which is what the config bundle uploaded here is set too. The extrusion width is set to 1mm for perimeters and 1.2mm for infill
• If your part needs to be an exact height, you can try to set the first layer to a value that give the desired final total height (first layer height + 0.75mm*layers = desired height)
• Can also try out prusa slicers cool feature of variable layer height, but never done it who knows what will happen. This should divide the object into vertical sections, which higher detail sections printing at a low layer height, and low detail sections print with a higher layer height

Hardware

• 1mm CHT nozzle installed (high flow)
• screen is Big Tree Tech TFT35-E3 V3.0
• mainboard is Big Tree Tech SKR Mini E3 V.0
• power supply is Mean Well RSP-500-24 (the good one, not first release of this printer that had a shitty one)
• Printhead is Micro Swiss Direct Drive and All-Metal Hot end
  • https://store.micro-swiss.com/collections/ender-5-plus/products/micro-swiss-direct-drive-extruder-for-creality-ender-5

• Probe is official BL-Touch (which is stock on the E5P)
  • it should be set and forget, don't think it needs to be recalibrated ever unless some hardware thing changes
  • can use 'babystep' feature to live z-adjust during printing
  • refer to this for setting the probe offset https://www.youtube.com/watch?v=y_1Kg45APko

Direct control of printer

To use pronterface to control the printer, first power up the printer, then connect the usb cable to your computer. On win10 it should auto-detect and possibly install 'maple' (wtf that is lol). Baud 115200

Calibration notes

• using the built in e-steps I got 137.85 steps/mm (this is in the firmware, in the slicer you just change the flow rate)
• at 220C and using PLA, got a max volumetric flow rate of 17 mm^3/s
• at 250C and using PETG, got a max volumetric flow rate of 19 mm^3/s

Print bed usage

The glass plate has a magnetic underside which as been heat fused to the aluminum bed lol. So it is more or less permanently stuck on there. Use the spring steel PEI plate, secure it to the black clips.

Wait for the PEI sheet to cool before removing your prints, take it off the bed and it will cool faster. PETG can rip off the PEI coating if it too hot.

Slicer Settings

Use the config bundle for prusa slicer, a copy is in this wiki under 'usage' and another copy is on the USB drive.

Keep in mind that this printer has a 1mm nozzle installed. The slicer settings I uploaded set the line width to 1.2mm and layer height to 0.6mm. So for an object with 1 perimeter is the equivalent of 3 perimeters with a 0.4 nozzle (so decently strong). So for most objects 1 perimeter and 3 top/bottom layers is plenty of plastic and will be strong enough. This will save a shitload of time!!

A few random printing tips

• just pray to the right god lol
• there is a big bed on this printer that takes like 10 min to heat up, so it could be wise to set the bed to heat while you slice your file

Octoprint at octopi4.hacklab.to

I wish...
