Finally got my JTech 7W to turn on and burnt a ruler onto my wasteboard.
Mostly. The numbers on the ruler did not come out right.
It won’t burn curves/arcs. My next test was to try a design, so I naturally chose the Onefinity logo. Same problem. I can see the laser dimming or turning off when the machine tries to move on 2 axis at the same time, such as following an arc or curve. Picture is attached.
Anyone know what to do about this?
I am using Lightburn for laser design and gcode generation.
Yes. Something the video doesn’t mention though is to set the tool type to PWM. Luckily, smarter people than me inhabit this forum and had already posted that nugget.
So, I looked at the gcode, and there are no suspicious S codes being set to alter the power level. Is there anything in the 1F or JTech controllers that could be fluctuating the power independently?
After talking to the guys at JTech, I sent in my controller. It seems that the signal voltage on the Shapeoko3 is lower than the Onefinity and this was causing the fluctuation. They replaced a resistor on the board and it seems to be working fine now.
