I just realized that I actually did receive some jumpers with my kit, I feel like I should have realized this late in the game. I only got one jumper per driver though so I installed them in the 1m slot, i.e. the 1/2 step slot. Then I went to measure the travel of the printer and it went 7.5mm per what is supposed to be 10mm. I guess the jumpers did their job. I'm going to use to calculator to try to get the right values for the firmware. I jumped the gun and tried to print a cube and still when the bed finished heating and it went to start printing the y axis just tried to go way past it's travel and the x axis went way off to the side to a point where the extruded wasn't even over the bed anymore. I think this issue has to do with cura and the object location in the bed in the gcode. I think it's telling the printer to print the object in some crazy location. What software do you use to set up (scale and what not) your prints?
Thanks a lot

I got the accuracy thing fixed but now my printer just goes absolutely wild when I ask it to print a cube. It wont go past its limits anymore but it will be going all over the place when the cube is only 10mm^3. Could this be an issue between the Cura to Printrun gcode transfer?

I have been doing some research on how to check voltage on the drivers and from what I have been seeing it seems like you probe between the trimpot and the ground pin on the driver, and also that there is a Vref test point. Yet when I try this nothing is read on my multimeter. Once I figure it out how do I set it? Do I adjust the trimpot to get the right resistance across all of them? I measured the resistance between the trimpot and ground and it was around 6.5 for all of them +- about 0.2. I later realized that I need to find the Vref test point to measure the voltage but I could not find it on my stepper driver.
Thanks
