Hello Lightburn, Humbly glad to be here. I have a chinese (from ebay) Laser 500 x 700 (red and back) with a Ruida 6442 controller/ Over the last couple weeks Ive done some upgrades. I removed the “dumb” motor which controlled the Z table up and down and installed a Hybrid stepper motor which I found the motor and driver n ebay for 80 bucks. I know nothing about stepper motor torque and the 4 post screws looked like it may be a job going up and down. with a great search I found the correct wiring diagram so if anyone is interested in how I did my Z axess ill be glad to offer what I had. after installation I initially had speed problems, mainly it went so fast it caused itself to freeze after about 5 inches. I was fortunate enough to find someone on youtube who had a similar sized machine as mine also with a larger stepper motor. He posted a picture of his parameters he used RD works, I used Machine parameters in Lightburn and after 5 minutes, it worked perfectly. slowed down nicely. I actually wont know if the sensor works till friday when my new one comes. Because when I first tried out autofocus in Light bre, my table crashed into my laser head and sensor messing the works up. Opps. anyway Im sure this will all work.
So with the Z axis out of the way, I also purchased one of those inexpensive (100 dollars) rotary devices along with its own driver. I say that because most machines like mine come with a 4 pin aviation plug with a harness hanging from it designed to be plugged into the Y axis. I thought it would be better and easier if my U axcess had its own driver.
Well this is where im asking for help. I plugged in the U axis device, tried to do the same ting I did with my Z axis by copping down parameters from m,y own Y axis. It didn’t work, the roller device is still going to fast, heres the rub, I thought I was typing everything into the U axis spot in Machine Pariters in lightburn. Except when I went to move the Y axis with the machine up down controls the Y axis moved sub snail, Worse it only moved 1 inch either way. I did see somewhere where it asked for my roller size which is 1 inch about 25 mm. I may have put that in somewhere but dont know.
The simple question anybody have a Ruida machine 500 x 700 mm and be willing to give me your Y parameters.
Before I sound totally stupid. Before I did anything I thought I made a backup of parameters both in Light Burn and RD works just t be safe So now when I open Machine parameters in Light burn the box marked OPEN is greyed out meaning I can see it but it doesn’t click. Otherwise I would just load the backup.
even if I did that I would ask anyone if they could help ,me with parameters for my U axis. or im afraid Ill just bunk it up again.
