I am no expert, but it looks like you may be losing steps. I don't really know how to solve this problem, but someone here will be able to help. Just be patient and your problem will be addressed.

Hi there
check your belts thats mostly the reason.

I'm with the guys, it does look like a step issue but I've also seen crud on the slides do similar things.
Before going down that road lets rule out file problems to start with.

Things to check:
1. Your belt tension. They shouldn't be sagging, but not so tight you can't push down on them.
2. Missed steps. Run the file a few times over and see if the lines line up properly. If not, you're missing steps.
3. Run speed. If your carriage is particularly heavy, running it too fast can cause your belts to stretch, and you end up with wobble in your lines.
4. Gunk on your linear slides. Simple things such as sawdust, metal shavings etc stuck in the rails can create points of resistance, which in turn can lead to missed steps.
The wobbles in the lines look like you have a belt issue, but the disconnected line on the P is a clear missed step issue.
Probably not (i hope) but i've seen pulley's coming loose from the steppers.
This gave similar results..
The could rotate a little around the steppers-axis.

Yeah, also check all the grub screws on your couplings/pulleys, they love vibrating loose over time.
Hi alan
here is another part what has given me headache it was on the X and Y axis the idler the most have only one bearing in it I did put a second one in it, but another version is that the idler was worn out what means there was groves worn in it and this has driven me nuts till I finally found it replace the idler and who a la it works like a charme again.
greetings

Looks like a faulty motor or dirty shaft encoder..shaft encoder is a disc in the black part of the motor housing , you can pry the housing off by spreading it at the tabs in the groove and slide the housing out. Using a fine paintbrush, brush it and the reader off , be very gentle.
Hello ,
If the lines are not straight on X aixs ,the possible reasons are as following :
1.There is gap on X axis . Tighten the belts or fasten the screws on pulley .
2.Check the laser head is loosening or not .Try to fasten it .
3.Checking the beam alignment .
4.The temperature of the water is higher .
5.Change another fomat or graph and try again .
Hope it could do some help !

:confused: Can you explain what watertemperature has to do with this distortion ???Quote:
