I have had a 30W machine for a while now, and I had a need for faster and larger engraving areas, so I took the plunge and bought a 100w machine with an additional 300x300 lens. Now I cannot get the machine to engrave correctly. At the start of a pass it usually starts ok, but then it appears to lose power (only way I can describe it) during the pass and get inconsistent liney engravings that are different every time.
I have series of pictures, with both the supplied 175x175 lens and the 300x300 lens and I still get he same issues, but for the life of me I cannot remember how to upload photos to a post sorry.
Any thoughts. I have even put the 300x300 on my 30w machine and got a great result, just extremely slow to get the desired results.
Also, any rough calculation of power/speed changes required as you translate between the two lenses? For example if it were doubling the work area would I need double the power (or half the speed) etc or is it more exponential than linear?
Image 1 - First instance of the issue - 100% - 300x300 lens think speed was around 500mm/s - not gaps and different levels of darkness in lines etc (should be solid square of colour). setting were exactly same for both, but gave different results…
And just to show that I can indeed operate these machines haha, I had a very quick play with the 30w machine with the 300x300 lens and got very good results. All 100% power, both running very slow to compensate for lack of power available, the lighter coloured item was probably 1.5times faster if not a bit more on speed.
