HELP with images on how to assemble CNC Machine (external link)...
Below you will find parts and tools, which will help you to print and assemble CNC Machine. All axes are with NEMA 23 motors and ACME 8mm lead screws for better accuracy at the expense of speed (compared to belt driven axes). If you noticed mistakes, weaknesses in design, have questions or suggestions, know original part manufacturers or better alternatives (available in EU and US), please write or send link to [email protected] • Project page: Jocys.com/CNC
Parts were printed from PETG with Prusa3D i3 MK3 Printer. If your printer is not precise enough, printed parts may not fit into each other and may not look good. Spaces between some parts are 0.1mm only.
Electronics by TinkerForge (DE) supports various programming languages. I am using this CNC Machine with my own software for light tasks. My own software will not be available for download. Depending on what you want to do, you may need to use electronics by other manufacturer. TinkerForge allows you to write your own software, but you may need something, that exists already, and TinkerForge doesn't support that.
I hope, you will find this project or parts of it useful. If you made your own updates or changes, related to this project, please send me a link. I will add this link on this page.

Printing Settings for MCPP BasicFil or AmazonBasics PETG Filament on PrusaSlicer
... for TEXTURED PEI Powder-coated Spring Steel Sheet.
For BIG parts to stick on TEXTURED PEI Powder-coated Spring Steel Sheet, I increased recommended bed temperature from 60-80°C (for AmazonBasic and MCPP BasicFill PETG filaments) to 85°C (First layer) and 90°C (Other layers). I printed BIG parts in my own Temperature Controlled Enclosure. Temperature inside enclosure was 35°C. E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems.
Modified settings: PrusaSlicer > Filament Settings > Prusament PETG > Filament
• "Extruder: 240°C".
• "Bed: 85°C / 90°C".
Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Layers and perimeters
• "Ensure vertical shell thickness: disabled" - I had problems with thin 45° hanging angles when it was enabled.
• "Perimeters: 6".
• Seam position: Rear - I printed most of the parts with "Rear" setting selected. It created line at the back of the parts, but front and side surfaces were perfectly smooth.
Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Inflill
• "Fill density: 80%".
Modified settings: PrusaSlicer > Print Settings > 0.20 QUALITY MK3 > Speed
• Reduced printing speeds (10-25-180-400). Slower speeds results in smoother and glossier surfaces without matte areas, reduces printing noise with vibrations... lesser probability for corners of big parts to unstick from heated bed, because of shrinking.
• "Travel: 180" - low speeds (like 25) creates surface blobs after long travel distances.
• "First layer speed: 10" - for better adhesion.
Modified settings: PrusaSlicer > Printer Settings > Original Prusa i3 MK3S > Custom G-code
• I added few lines to G-code to remove filament blob on nozzle right before printing starts and raised intro line to reduce wearing of steel sheet plate surface.
G0 Z50 ; ADDED LINE - NOZZLE BLOB - Z up 50 mm to clean filament blob from nozzle before printing.
G4 S5 ; ADDED LINE - NOZZLE BLOB - Pause 5 seconds to clean the nozzle.
G0 Z-50 ; ADDED LINE - NOZZLE BLOB - Z down 50 mm to initial position.
G0 Z0.5 ; ADDED LINE - INTRO LINE - Z up 0.5 mm for less intro line adhesion to prevent steel sheet plate surface from wearing.
G0 Y-1 ; ADDED LINE - INTRO LINE - Y shift 2 mm intro line default start position to prevent steel sheet plate surface from wearing.
For better quality and safety... I printed majority of parts separately.
