Hello. Yesterday i connected my step motor to GeckoDrive G210 driver. G210 connected to PC through LPT port, common +5v coming from PC PSU.
But motor rotates well only in one direction. In other direction motor rotation is very unstable and it stalls.
If i connect G201 instead of G210 - everything works well. Is my G210 broken? It seems like G210 has wrong understanding of DIR signal :confused:
Make sure that your header option on the g210 is set for the proper common, which I believe is common 5v to match the g201.

rqet,
Your problem is the parallel port outputs 3.3V signals while the G210 requires 5V signals. You will have to get a breakout board that buffers the signals to 5V levels.

Thats right, thanks. I connected 500 ohm resistor between DIR and +5v terminals and now it works ok!
It only seems to work. You cannot pull 3.3V outputs up to 5V. Measure the DC voltage with a multimeter; you will get 3.6 to 3.9V. The drive will be susceptible to missed steps. You really need to get a breakout board.
