So I recently got my Lulzbot Taz clone up and running.
It's running a cheapo Geeetech Rambo 1.2 board at 24v (I soldered a 15 amp fuse holder to it)
I've had two problems so far:
After its been running for a while, the Z Axis steppers 'click'. They twist and twist back very slightly at a regular 3 sec interval producing an audible click sound.
Every so often it loses a z axis step and I get a squished layer. Unsure if its both steppers but it looks like it.
So, similar problems on RAMPS suggest increasing the current. The Rambo calibrates on the board.
I'm not sure if this is the result of getting a cheap board and running it at 24v or what the issue might be.
Any suggestions?
