I have been controlling my DIY longmill with an Arduino and a CNC shield V3 with DRV8825 stepper drivers. That seemed to work fine up until today, when it decided to release the dreaded magic smoke.
I was thinking that I should upgrade to the beefier TB6600 drivers used on the longboard. And if I’m going to do that, maybe I should just build a DIY longboard (the Gerbers were shared by Sienci, and I have fabbed PCBs before). That brings me to three questions:
- Has anyone built their own longboard controller yet?
- Are there any errata that I should be aware of?
- Does anyone know where to get the TB6600 drivers used on the longboard? There are loads of TB6600’s on AliExpress, but they all have screw terminals soldered to them. It looks like the ones Sienci uses have pin headers instead, which in turn get soldered to the longboard PCB.
