I’m having reasonable success with the Lowrider, got a couple of projects I’m hoping to get cleaned up to post here, but I’ve been running into a few problems while trying to cut some pieces for this bed; http://craigdstover.com/flatpack-bedframe/
I’m cutting at 600mm p/m, any slower and my router gets a bit too hot, with a 6.4mm two flute straight bit at a depth of 4mm. It’s 18mm ply, but I’m under the impression this shouldn’t be pushing the machine too hard.
I’ve had issues with USB Cable interference with previous CNCs so on the Lowrider I’m only running it off the SD card, so I dont think it would be an interference issue, unless its 230v interference along the X axis stepper motor? That said, I have them spaced as far as possible apart and the stepper is wired in stranded cat6e
I’ve found that either of my Z steppers sometimes suddenly stop holding, generally one at a time. It can be while cutting, can be while setting the origin.
I’ve also had issues with my X axis binding up, today it was while cutting this attached area.
Stepper motor current is set to;
X axis - .80v
Y axis - .78v
Z axis - .82v
I’m wondering if my power supply isn’t quite beefy enough, the steppers are 1.7A each, with the supply only being 3A - Initially I assumed that the 1.7A rating would only be a stall current, but now I’ve typed that, I’m thinking that could very much be the problem…
Any other ideas?
