Laser Master 2 Pro S2 - smashing into bottom rail when framing

Hi! I’m brand new to Ortur and LightBurn. I set up my first project and set to absolute coordinates. The laser homes to bottom left corner but when I hit frame, it goes to a completely different spot and slams into the bottom rail. I’ve checked the settings and it’s set appropriately at 400 x 400 work area. Are there other settings somewhere or is there a way to reset the machine?

It’s possible you have an offset configured on your laser. Can you complete a Homing operation and then run these commands in the Console window and return results please:

I don’t see an offset configured and I don’t see anything odd in your configuration.

However, you should update your firmware when you get a chance:
Ortur – Firmware Repository – Ortur

Can you take a full screenshot of LightBurn and also a screenshot of Edit->Device Settings?

I’ll update the firmware now thanks!

Firmware updated successfully. I was hoping that was the quick fix I needed; not so lucky.

Let’s try one simple thing now that you’ve updated the firmware. Will move to other things if that doesn’t work.

Issue these commands in Console:

$RST=*
$I
$$
$#

Please return results.

Power cycle, then retest.

I just power cycled - am i running the commands again or testing the frame?

The frame please. It looks like the reset took and you have new “defaults” loaded so wanted to make sure there was nothing going on there.

Retested the frame - still outlining in the wrong spot and hitting the bottom bar

This is my piece - I have the wood located in the middle of the laser grid…when I frame - it goes from home probably 2 inches to the right of the design, across at about the cup/oz/tbs grid and down into the bar

Odd. Let’s start from basics then now that the more common things are out of the way.

  1. Can you confirm that the laser head homes to the lower-left position on power on
  2. Can you confirm that you’re not manually moving the laser head by hand at any point after the homing process?
  3. Test the arrows in Move window. Can you confirm that they work as you expect? Left goes left, right goes, right, etc?
  4. For these next steps be prepared to pull the power on the laser in case you get a crash. Enter into Console. Does the head move to top-left?
G0 X0 Y400
  1. Enter into Console. Does the head move to top-right?
G0 X400 Y400
  1. Enter into Console. Does the head move to bottom-right?
G0 X400 Y0

Report back on results please for each item.

So we had to move to direct messaging since I maxed out of replies here but here’s the replies going forward, which thankfully fixed my problem:

Here’s what I got:

steps 1-3 yes
step 4 nothing happened:
G0 X0 Y400

ALARM:2

Step 5: moved to about 26CM and stopped

Step 6: moved bottom right

[berainlb]
the behavior for steps 4-6 are odd and correlates to the framing issue you’re seeing.

I noticed something on one of the screenshots that I hadn’t noticed before that may be related.

I think your Y-axis limit switch may not be getting engaged properly. Or possibly not disengaging properly. The fact that the laser can crash into the bottom rail is also telling that there’s something wrong with the Y switch.

When homing, can you confirm the following series of events:

  1. Laser head moves down and to left
  2. Each axis switch is engaged. First one, then the other.
  3. after the 2nd switch is activated, head moves away from switches a short distance
  4. Head moves back toward switches at a slower rate
  5. After reengaging the head moves away slightly and comes to rest

Can you physically examine the engagement of the Y-switch? Is it engaging freely and easily? Or is it just barely able to engage or possibly obstructed in some other way?

If all those things are fine then please continue with this test.

  1. Home laser
  2. Go to Move window
  3. Hit Get position and record the current position. This should be 0,0 but make special note if it’s not.
  4. Use up arrow to move up 10 mm at a time. Note position. Has Y increased by 10 mm?
  5. Keep going up and noting position until you either hit the top or otherwise prevented from moving up.
  6. What is the maximum value reached and how far up the frame is the head?

Btimo:
1-5 - yes
Y-switch seems to be engaging fine. I hit frame again and it just framed the wrong area. I hit frame a second time and it crashed. Is it crashing because I didn’t home it before hitting frame again?

The Y does change every 10mm and stops at 400 which is at about the 27cm mark on the frame.

[berainlb]
I suspect you’re losing steps if that is the case. Check belts for proper tension. There should be no slack in the belts. Focus on Y axis. Belts should be taught but not stretched.

It could also be that the pinion on the Y-axis motor is loose on the shaft. There is a grub screw on the pinion that is meant to tighten again the flat portion of the shaft. Make sure there is no movement if you try turning the pinion in either direction. If there, align pinion and tighten grub screw. There should be a second grub screw on a different part of the pinion. Tighten that one too. It’s possible that there are 2 grub screws stacked on top of another. In that case you will need to remove the top screw to get to the bottom one. Make sure the bottom is properly fastened before replacing the top.

Btimo:
OMG you’re the best! That fixed it! I tightened everything up, homed it and went through the intervals and it finally gave me a full work area. I homed it and hit frame and it worked! Thank you SO much for your help, you have no idea how much I appreciate it! I really thought I was going to just have to scratch my ideas and return the machine because I couldn’t figure it out.
