In configuration.h find this line: #define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} // (mm/sec) And change Z feedrate (the one i made bold) to somewhere between 3-5mm/s depending on how fast your motor can go. It could also be to low current setting on your z-axis driver. If you drive two motors you need more current on Z-driver. Jesperby Kenzu - RAMPS Electronics
Had a look at the file, but it does not make much sense for me, sadly :-( Any help? Will try again when i get my uln2003 setup put together.by Kenzu - Firmware - experimental, borrowed, and future
Can i use Teacup on a atmega328 to drive a uln2003 darlington array and a unipolar stepper with normal step signals and not dir/step/enable? with 2 or 4 wire control like this Thanksby Kenzu - Firmware - experimental, borrowed, and future
Check your jumpers/solders on your x-axis. Maybe it's switching from 1/8 stepping to 1/16. I don't think it's a software problem.by Kenzu - Firmware - mainstream and related support
If you size up til gear/baerings, then maybe you could fit dual bowden hotends :-) Looks niceby Kenzu - Polar Machines, SCARA, Robot Arms
@droftarts My google fu is not good enoght :-( Can't find any cad files for STD profiles.by Kenzu - Developers
I would love the get the STD profile too :-) STD S2M and S3M Thanksby Kenzu - Developers

You can see it here in this Minebea Stepper Motor Part Number Decoding Tableby Kenzu - Stepper Motors, Servo Motors, DC Motors
The ending g4vs is a customer kode. I.e for special axel, gear and so on. I know this because i work with copy machines and they use alot off the same motors but with different gears on. :-) So don't think about the g4vs. If you look here u see that your motor is a 400nNm in unipolar setup and 500nNm in bipolar. (they should be hybrid motors as all others) :-) Some fine motors Jesperby Kenzu - Stepper Motors, Servo Motors, DC Motors
