Ok... to clarify... you said that you "updated" it.

Does that mean that I should use the one for the plastic machine again... since it's been updated...
or should I download the one for the metal machine and use it?

Please be specific.

I downloaded G2s for the plastic G2s machine... NOT the firmware for the metal version G2s.

Yes this is the Firmware I compiled and uploaded to my G2s... the problem is still there.

Oh... almost forgot... another problem. When trying to user Extruder 2... all axes (x, y, z) will move toward home (and ignore limit switches) when a extrude command is given. There is a thread about this problem... I posted... but, no reply. You claimed months ago that you thought you have it fixed...

Because this is DELTA printer and all towers (X,Y,Z) must be set to the same Steps/mm.
So... as a work-around if I make X & Y accurate I then must compensate the Z movement by scaling.

By the way... I uploaded new Firmware and no longer have the problem. All axes movement are accurate now.

I am having the same problem when trying to us both extruders. Is the firmware fixed yet. I just downloaded and uploaded the November Firmware... but, dual extruder problem is still there. When can we expect a fix? FYI: I purchased my G2s back in July 2015, I really like it. Took a bit to get it to ...

Factory settings for X, Y, Z are 80 steps/mm. Example... If I issue a 50mm move on X axis the actual is 57mm. Note that the z axis moves correctly 50 mm if issued the same command.

That is only a parameter and only is valuable IF the code that does the calculation, that uses the parameter is correct. So your reply did not help me. It appears that you don not understand enough to be helpful. Very frustrating! Your inability to provide appropriate information is not good for bus...

X and Y positions are consistently NOT accurate. However, the Z Axis is accurate.
My workaround was to set the X, Y, Z steps/mm from 80 to 68.8 steps/mm then scale the Z axis to compensate.
This work-around is barely usable and must be done for each file loaded.

Any suggestions?

I too need the original firmware that came with the machine... for the same reason. My G2s was NOT set up properly at the factory... prints quite well but, movements are not accurate. Z Axis movement is accurate but, X & Y are not. I created a work-around but, tired of having to adjust scale for eac...
