Hi guys,
I recently installed a set of TMC2130 v3.0 drivers from BigTree Tech onto my RAMPS 1.4 board. They're all set up for SPI and used the included harness to connect it all then made single jumpers to connect the diag pins of the X and Y to the board for sensorless homing. I have an LCD so I had to re-assign the pins, no big deal. I also added a BL Touch at the same time.
The problem I'm having is the motors seem to run perfectly normal with normal travel moves. When I try to home though they just buzz and vibrate and don't do anything. I'm pretty sure I got the RMS current set properly, I used the Teaching Tech YT video on calculating the current. I've tried raising and lowering the current to no avail. The X and Y just buzz and trip the sensorless homing. The Z buzzes until I tap the BLtouch sensor then it raises slowly and drops slowly until the sensor is hit again.
Once the axes are all homed I can move them in Repetier or with the LCD and they move fine - smooth and silent. It's just homing moves that seem to be the problem. Any ideas on where to start to get this sorted? The printer is a Folger Tech 2020 i3, stock motors.
Also this isn't a big deal, more of an annoyance - is there a way in the LCD firmware to get the rotary encoder to act normally? By normal I mean rotate clockwise to increase the value/move the cursor up. It feels backwards now being that you rotate it counter-clockwise to raise the number.
Thanks in advance
