CTR+J Jump To problem

As part of my ongoing problems I found that after a recent power outage I tried to use Jump To, to restart the job at a certain point. I chose a line of the code that was a little before the break. I followed the Jump To instructions but, checking the axis co-ordinates there was a serious difference between the actual G-code in the program and the numbers on the Jump To window.

The actual job G-code axis are X 1.4428, Y -0.9385 and Z -0.3785 at the particular line I entered into Jump To.

The Jump To axis numbers showed X 36.6470 (which would put the spindle in another room!) Y -23.838 (which would put the spindle at the bottom of the spoilboard and a long way from the workpiece) and Z -9.614 (which would cut through the spoilboard and the machine base itself.

I can't figure out why the Jump To co-ordinates are so out of kilter with the G-code. The Jump To numbers are totally unrealistic and I have no idea why they are what they are?

Hi Robb,

Just read your post and realized the problem you are having with the Jump to line is a software bug.

In v3.46 the jump to line didn't work properly with imperial. It output the values in metric instead of imperial.
It was fixed in subsequent software updates.

Cheers

That's a blessing (sort of). Thanks so much Peter.

I've been trying everything to get it sorted. Now I know I've been wasting my time somewhat.

I still do not have the latest upgrade (3.48). I did raise a ticket asking for the upgrade to be sent to me but, I haven't had any response so far.

Is this bug 'fixed' in 3.48do you know? Would I be able to upgrade and use a 'working' Jump To to resume the job, that's still calmped down on the spoilboard waiting to complete?

Hi Robb,

The bug was fixed in version 3.47 so the latest version will also work.
Once you update the software you can use the jump to line to continue your cut.

Cheers

Have installed 3.48 and discovered a few minor differences to my earlier version 3.46. The MPG is different in how it responds. Instead of a click at a time it now has an overrun on each setting on each axis.

Jump to: I ran Jump To to try and salvage my job. The Jump To window now shows (almost) correct, Imperial, axis values for a particular line of code. Clicking run and the spindle moves to the X and Y axis locations for the line. The spindle powers up to the correct speed but, doesn't descend. I've run Jump To a few times (using different code lines) and each time X and Y move to locations, spindle starts but Z doesn't descend.

Any ideas folks?

Hi Robb,

The jump to line coordinates you describe as almost correct. How far out are they? Please take into account that actual position is determined by your axis resolution so MASSO will move you as close to the specified position as possible. For example, and I exaggerate here for simplicity, if each step moves 1 inch and you want to move to 5.75" then it would have to move to 6" as it is the closest you can get.

With regards the Z axis not descending and proceeding to cut did you press the cycle button after reaching the X,Y position?
It is also possible that if you have a 4th axis like the A Axis that it might move this axis before continuing with the cut and if you don't have it connected it might look like it is doing nothing. Press the cycle start button a couple more times and see if the cut starts for you.

I just tested Imperial Jump to line in 3.48 and it worked for me.

If you still can't get it to work please post the Gcode file so I can try it.

Cheers
Peter
