Only one of the gantry joints move was created by Malteser01
Hello there!
I have recently mostly finished my CNC mill. It is a 3 axis moving gantry, with two motors on the Y axis.
After lots of troubleshooting and learning about linuxcnc, I finally (!) got all 4 joints to home.
I can jog X and Z as I should be able to, but with Y that's a different story: only one of the Joints moves during jogging.
After only implementing the 4 joints and declaring joint_1 and joint_3 as Y in the ini didn't work, I tried adding loadrt gantry [.....] . The syntax with this one is a hassle. About 3 hours later I got linuxcnc to post with it, only to find out that it didn't change anything at all.
I can later (got them on a thumb drive right now) post my .hal and .ini if that helps. Maybe someone knows an answer already.
Thanks to you all in advance!

Parallel port +bob. Mesa was too expensive for me for a proof of concept.
I found the gantry command (if it's called that) in the linuxcnc documentation, and thought that it might solve the problem.
Thing is: the problem stands with or without loadrt gantry. All the axis home, but only one of the ys moves while jogging.

So, now that I finally found time and access to a pc, I can share my .hal and .ini
I really appreciate any effort anyone puts into this.

Okay then, I'll try stepconf again.
Hoe would I then teach the machine to accept a as y2? As far as I'm aware, there's no setting in stepconf for that.

What version of LinuxCNC?
2.10 has tandem limits so it should have tandem joints also.

Setting tandem axes is done when homing. It is all covered in the documents under the heading "Homing Configuration"
You need to read it a few times before it sinks in.
each tandem joint needs a negative HOME_SEQUENCE
