Machine is homed but not zeroed

LightBurn Software Questions
1

Hi everyone,

I recently extended my Aufero Laser 2 to 431mm x 952MM and added home switches. I have figure out how to tell both lightburn and the controller the new size, and I have gotten the machine to home. However, at the home, the laser shows X-428.00 Y-949.00, and appears off the workspace. The origin is set to lower left, as is the home position.

You have an offset. I’m not sure how to remove this manually so typically need to reset for this to be resolved. Can you run this in Console:

$RST=#

You likely also want to report machine position instead of work position. I believe this is the value you want:

$10=2047

Can you power cycle and then retest?

3

I have reset numerous times with the same outcome. I will try the other code

4

I have run $rst=#, #10=2047c and power cycled. There is no change when running $#. I still see HOME:-428.00 -949

5

Ideally HOME would go to 0,0.

Can you confirm that the machine is homing to the front left of your machine?

If so, I think you could override this behavior but it’s not ideal. Try this:

$10=2046
G10 L2 P1 X-428 Y -949

Power cycle and retest.

6

That seems to have worked. I tried that but failed to power cycle. But I have now lost my continuous jog. And when I do jog say 200mm on the Y, the machine goes far past 200mm on BOTH X and Y

8

Annnnnnnnnd back to square one. As soon as I enabled $j it went right back to the same problem

9

I have to run
G10 L2 P1 X-428 Y -949
after EVERY job or jog.

10

Can you save your settings and try a full reset? Or have you tried this already?

$RST=*

Make sure that you get a positive acknowledgement that it’s been reset and check $# for offsets.

11

After saving my settings, running $RST=* I can confirm there are no longer any offsets. HOWEVER (and I should have mentioned this sooner) I still have to for and change $44=3 $45=0 in order for it to home. Once I do that I get the offsets again.

12

Can you confirm your laser homes to front-left?

If you don’t issue $J does the machine behave properly?

Can you try again and when things revert behavior can you run these commands in Console:

$#
?
13

I can confirm that the machine homes front left.

I can also confirm that after $rst=*, and laod my saved settings, the machine behaves properly with $j enable and disabled.

Its the moment I change $44=4 to $44=3 and $45=3 to $44=0 that the offsets come back.

14

Can you reapply the G10 command and retest?

If it fails, what is the output of:

$#
?
15

$10=2046

ok

This is WITHOUT making any chages to $44 or $45, therefore homing fails

16

Can you reapply the homing fixes, Then run the G10 offset?

Then test and get it to fail as you say. Then run in Console:

$#
?
17

I’ve left the shop for the night. I will do that in the morning.

18

sorry for the delay. I had reached my max allowable replies that day.

The following is after $rst=* - reload saved settings - made corrections to $44 and $45 - ran the G10 offset - power cycle - “get position” - $#:

ok

19

When do you lose the G54 offset? Or rather what causes it to disappear?

20

It happens as soon as I home the machine.

21

I should specify, its AFTER I change $44 and $45. The machine fails to home if I dont change thoes
