Time to share my hobby build of a lowrider. I’ve been planning some form of MPCNC for a few years but always lacked the space. Now we have moved house and I get to have a workshop (garage)… the build has begun!
Unfortunately my PLA filament 3d printer is out of action until I replace the unserviceable Melzi board with something more suitable … so some parts have been printed by my brother in PLA and some parts using my resin printer.
Router of choice is the KATSU copy of a Makita model. It involved a change to the mounting holes for the router using info found on the web.
Y plates cut by hand using stick on paper template.
Router plate cut using my existing cheap chinese CNC
Board is a MKS Gen 1.4
software is GRBL. I use GRBL on my small CNC and like its co-ordinate system and understand how to manipulate settings etc. It fits in well with my workflow
- design in Fusion 360
- generate Code in Fusion 360 post processor for grbl
- save G code to network drive
- Lowrider is connected to an old Dell Optiplex fitted with a touchscreen.
- G code loaded to GRBL… and start cutting!
Only a few test cuts made so far and no real production yet until I can ensure all is robust enough for a prolonged cut.
Things to do:
- tidy up wiring… I’m still using a breadboard to get my drivers running in a series mode.
- Send x motor wiring through cable chain
- Set up dust extraction… change of router means change of method
- Use LR to make some accurate Y plates to achieve closer to a square setup
- Add endstops
Problems I have encountered:
- Slightly out of square at build and most likely due to handcut Y plates.
- tightening M4 nuts on side plates for y axis. Cant get a grip of them easily!
- One of the Z motors struggled to lift weight of router assembly which wasn’t helped by the weight of the control board and wiring mounts. Those are now shifted to the side of the Y plate and all is well again so far
So thanks to all that help on this forum, I have sourced the answer to many of my glitches.
Hopefully more updates as build progresses
