jogging problems

[Gareth52]

Hi all,
Been using Mach3 for about 3 months now, with few problems. Today I rewired my motors from parallel to series (because I found that my driver boards could only deliver 3 amps to 5 amp rated motors and the resultng loss of torque was proving an impossible obstacle)
When I started Mach again, the motors will only jog at about 3 to 4" / minute. If I put code into the dro, they move at normal speed (15"/min). I have jogging set to 100%. I rebooted several times and checked all settings, but can find nothing obvious. In any case I did not change anything in Mach 3.

Can someone please help me?

Does the feed DRO show it only moving at 3-4IPM when you jog?

I will use the x axis for reference here. (But all axes have same characteristics.

In jog mode the DRO shows a feed rate of 2.2.  If I input a go-to command, the axis moves normally and shows a feed rate of 14.88 (it is set to 15"/min). If I tell it to go to zero it moves normally too. I tried pressing shift key whilst jogging, but no increase in speed.
The problem is that I do not have a fixed home position. That depends on the workpiece and I use jog to home the cutter before running the program. Obviously this is now going to be very difficult to do.

Ok thats good in a way as it means I can replicate here, if you attach your xml I will see if I can find the issue.
Dont see how this would make a difference to your offset position but we can cross that bridge once this has been resolved.

Thanks for the help Hood. I've attached the XML file

Initial observations of the xml show you have X-- limit set to the same port and pin as the X Step also you have Input 1 set to the same as the E-Stop, the latter may be fine but the former is wrong for sure as pin 3 is an output pin.
Having said that I am able to jog just fine, jogging X I get 13IPM showing and that is what your motor tuning is set at, Y is 16IPM and thats what I get when I jog.
Does this happen if you use the jog buttons on the flyout screen or is it just if you jog via keyboard?
Can you try a different keyboard to see if that helps?

Fixed!!!! Thanks a lot Hood. I disabled the limit switch settings and then reset automatically and everything works fine. The jog is still a bit slower than the run speed, but that is not a problem. Also the motors are a lot quieter now (an added bonus)

Thanks again.

Jog shouldnt be slower so not sure what the issue is there as I got full speed with the jog. Had a typo above I think as I said 13IPM but if I recall it was 12IPM which is what your Velocity was set to.
