It doesn’t look like much but there was a lot of work that went into getting to this point. I’ve set up LinuxCNC to use on my lowrider. I can now home each motor individually but synced by axis, automatically turn on and off my router, tool change using a touch plate to set z height, a live jog (mea…

Very nice what controller? I’m impressed for sure looking forward to the how to :space_invader::space_invader:

I have a refurbished Dell Point if sale PC, going to sainsmart parallel breakout boards and tb6600 stepper motor drivers. Although I’m very curious how it will work with the spare pololu stepper motor drivers I have. I plan on trying them for the affordable option on how to set this up

@dkj4linux has a thread using linux cnc and a ramps board (or was it a grbl uno shield?) with drv8825 drivers. I dont think he had dual drivers and auto squaring working though.

Yea I saw it and it was definitely some of my inspiration.

This was the thread where I used an inexpensive Mach3 parallel port breakout board and CNCshield V3… without the UNO. Basically used the shield just as a breadboard for the DRV8825 driver modules. DId nothing fancy – no squaring or dual drivers… just 3-axis movement.

Missed that one I think will review thanks

I already have the three axis squaring done. I’m working on getting the touch probe and tool change process down then I’ll make a post on how to replicate

First complex cut in foam with linuxCNC. This project has no less than 4 tool changes. I’d say it went flawlessly. I have a tool change down to less than a minute with extreme accuracy. I’d say I’m ready to publish my LinuxCNC setup and configs. Tomorrow I’ll do a huge writeup on how to replicate a…

Ooo, I’d want to build it so the clock’s hour hand stays stationary and the gear rotates, turning the other gear. :slight_smile:

I’m trying to decide if there’s a useful way to drive them so that a different tooth was touching each minute, but it was only in phase once per 12 hours, and there was some meaningful way to read it for each minute.
