I got a used small cnc gantry router that has 2 leadscrews with 2 steppers in Y axis.
How can configure this to have 2 Y axis steppers run synchronized?
I use linuxcnc 2.8 from parport and soon from mesa.

The easy way is to output same signals on two pins on parallel port for both drives, the harder but much more useful way is to configure it as a gantry with two Y axis. Plenty of tutorials on the forum and easy to follow on the man page.
Hell the first time i used it i did not even bother to look at any help, just did a copy of that same axis, change the joint numbers, changed the outputs to fit, added some lines to the ini file to reflect that it has two X axis and set the homing to -1 for that axis. Done! worked on the first try.

ive tried that with no luck, maybe a new update has messed with things? it homes just fine but when i go to jog the machine only 1 axis of the gantry moves. if i enter a mdi command (goo x.25) i get an error that the A axis cannot move because it will be out of range.
any ideas?
here is my ini/hal file
