Hello
I recently swapped the 20w module over to the 2wIR module and it worked very well but when I replaced the 20w module I have problems with Beeping Alarm, flasshing red light, Alarm1 on lightburn console readout, and some homing issue.
The module is Bumping as it travels along when going to frame a job and if I cut an outline, then home the machine and return to engrave the job starts not where it should…for eg maybe 2cm to the side.
When a job starts it works perfect for engrave and cutting and will fast travel over whitespace at speed with no problem.
It is only when Framing and Homing that the Bumping/knocking occurs.
The Control box has not presented a problem since the initial day the problem started.
All cables are secure.
I am first trying to establish if this is mechanical or connections or software/firmware related and I am using v1.7.4
would it be advisable to reload the firmware via sd card reader or replace usb cable. I am hesitant to remove pannels to look at mechanical components.
From the beginning the module has made little bumping noises while going to frame or home (it is not a travel speed issue as that is only 2000mm/min) but they did not interfere with the accuracy of the machine, but now it is more severe.
Thank you for your attention, any insight or knowledge is appreciated.
The only thing to home the machine is the end stop in the linear module (maybe an optical or mechanical switch).
What happens if you jog into the homing position, does it bump too?
Thanks for the response.
I haven’t tried jogging, I’ll give it a try tomorrow.
Today I downloaded the HMI 1.7.4 and put it on the sd card and deleted the original HMI 1.7.4 file. I ran a job with no issues but didnt get to really test it.
there were a couple of minor bumps as I homed before shutdown but…
Since I got the machine it has usually but not constantly made a few bumps/grinding while framing or homing, A bit of a concern as it made me think something is broken or loose inside the gantry..but nothing serious came of it and positioning was always repeatable and exact.
I had instinctively figured its a mechanical problem (dont know if its belt or screwdrive slipping) but had a thought that a signal or power interuption could also cause such grinding/bumping, and as the control box was beeping and flashing red light and alarm1 could be usb cable related but that has not occurred since the initial problem.
I’d love to see whats behind those metal strips especially the X axis, as thats where the issue always happens (I think) as the module moves.
Funny thing is, while doing a job and fast whitespace travel there are no issues at all and I’d love to know if the framing/homing and cutting/engraving are controlled seperatly.
Anyway, thanks for the suggestion, I’ll try various speed and maneuvering/jogging tests tomorrow and also I think I remember reading something about removing those metal strips for cleaning so I might do that so I can actually see how the mechanism operates and if anything is/looks worn, loose or misaligned.
Regards
Pete

I was a bit busy since, but after reducing travel speed to 1500mm/m the symptoms are less and prior to framing/homing speed reduction I noticed there are severe bumps and mini bumps and either can happen at any time randomly during frame/homing..
There was one incident when it happened during engraving, where it stepped out by about 2- 3mm but other than that it functions perfectly.
Imagining!. what is potentially occurring, it also sounds just like a Toothed cog that can slip a tooth or more under some circumstances I also read a post on LB that mentioned the controller taking over the control once Start is pressed..so I now know there is a difference between Home/Frame..and Job control.
I will most definitely remove the metal strip to have a look, which of course I should have been doing on a regular basis anyway for cleaning.So busy learning software I forgot.

Took the head mounting and metal strip off the X axis and cleaned all and waxed. No sign of any misalignment or looseness.
The belt seemed to be at a reasonably good tension but did have some very minor scuff/scratches. At the slow speeds I have seen the issue of module bumping occur I would not imagin there was sufficient wear or other issue to cause this…at least on the x axis, although I did not remove end caps to look for possible issues at the cable in side yet.
It was nice to actually see the workings inside. Reassembled the axis and took out the module fan for a good clean..lots of deposit but ok for six months of light work.
One startup and frame test went perfect.
If issue happens again, I will remove the strip and run the framing so I can observe the workings while in motion and also inspect Y axis.
One thing I noticed was the laptop (hp probook, bought as refurbished) Twice made a sound like when you connect a device, for no reason, ..this could be significant.
Still very happy I bought the ray!

Hi all
Further to the issue I was having with the ray. I was delighted to eventually discover the source of all the problems.
It was vibration from two 5mm spacers I was using at the four corners and a little block of wood each side of the spacers to keep the machine in position..Not tight, just snuggly in place. (my own design and built enclosure).
The tiny vibrations of the machine were traveling through the axis frame but had nowhere to disipate to, so I guess they just kept building up causing noises and somehow making the stutter in axis travel.
I placed apiece of foam on top of the spacers at each corner and the issues disappeared completely and the machine operates perfectly.
