I have a 90W Chinese machine I bought from Itech in Jinan China.. Im currently having cutting issues with it, and kinda lost now on what to check for problems.
Heres the backstory for it...

Ive been cutting 1/4" cast acrylic using these settings:
1 pass
5% speed
98% power
factory frequency was set at 20000
meter reads around 26 mas

thats what Ive been using for over a month (since I received it). I was told by someone else that they were able to cut ALOT faster using less power on a 60W.
does that sound right for settings ?

Now to my current problem..this morning it was cutting fine on those settings..then I started playing around with testing engrave settings...but now that Im back to cutting, using the same parameters, it will only get about 1/4 of the way through. yes, my mirrors are aligned..and lense is clean. any help on what I should check would be appreciated.

what is your meter reading I had a problem after I engraved where my meter was only reading 15 ma when it should have been 25 and it wasn't cutting all the way through. I has to go into the minimum power setting and bump it up from 30% to 85% then my meter was reading 25 ma like before
