The formulas are different for every type of motor driver. Use the information from your driver’s manufacturer.

I don’t know why these were published as AMF files. I changed them to STLs.

The nozzle sits slightly farther forward with this mount, so it does not home over the bed. This was necessary for the parts to fit, but I think it is also preferable since it prevents the nozzle from driving into the bed when you home. You do not need to adjust the Y endstop unless you are worried about losing a couple millimeters of print area.

I changed the direction and updated the CR10S E3Dv6 images. Try it again.

FYI, you cannot change the firmware configuration in MatterControl. This has to be done by editing the source files and recompiling the firmware. See the links above for how to do this yourself.

The only differences are X_BED_SIZE, Y_BED_SIZE, and Z_MAX_POS in Configuration.h. Your printer is an oddball size, so you should either use the 400 firmware or edit the 300 firmware and change Z_MAX_POS. You can reverse the motor direction by changing INVERT_E0_DIR. Alternatively, you can swap the wires on the motor. See https://forums.matterhackers.com/topic/3....

CR-10S firmware posted.

We’ll post the CR-10S firmware soon. I have it configured already, I just need to test it on a machine first.

I believe you will still need to use the dual mount. The Replicator 2X has a double wide carriage, so the single mount will not be wide enough to work.

Some kind of feeder is needed. We chose the EZStruder for this guide because it is inexpensive. Other options would be the E3D Titan or the Bondtech BMG. If you use something besides the EZStruder, though, then the mount design we provided will not work.

The fan on the Makerbot is pretty weak to begin with, so removing it is not a huge loss. If you find you still need additional layer cooling, you can get a small desk fan and point it at the printer.
