Laser always on when carving, creates travelling lines
« on: August 05, 2019, 10:56:33 PM »
Hi there! Newbie here. I just got my Elekslaser A3 Pro yesterday and I didn't know how complicated it is to operate  ;D I gave up on Elekscam so now I am trying Benbox. I successfully engraved something but attached is the result. I noticed that the laser is always on, so it created those travelling lines when engraving. Any ideas as to why it happened or the correct settings for it? I tried again on paper but the same result appears. The image I used is in JPEG and the Carve mode is outline - curve, as I find Scan by Line and Scan by Z-shaped too slow and burning everything. Sorry, total noob. Your help is much appreciated  ;)

It is necessary to match the firmware in the controller with the host application. An easy way to get started is by using a trail version of T2 or BCL. They support GRBL-1 firmware and have provisions for downloading and setting the initial operating parameters.

The older firmware used a different I/O pin on the embedded CPU which does NOT support PWM (Pulse Width Modulation). Some controllers have a jumper to select the pin. I would expect the always ON condition if you have the old firmware with a newer controller.
SARCASM - Just one more service we offer here.

Oh, I see. I'll try T2Laser then  :) Will get back again with another result. Thank you!

T2Laser with my Grbl 1.1e DEFAULT firmware should fix it, if not you have an older board and need to use the Non-PWM firmware in the custom menu but be careful loading random firmware as it's easy to "brick" the Nano.
