Hi,
I’m hoping to get some help with my problem.
First of all:
My configuration is:
Sculpfun S9 with S10 head. Controller is replaced with a Makerbase MKS DLC32. I use endstops at the top right corner
Previously I used the original controller and connected the S9 to a raspberry Pi with Octoprint. But that doesn’t work as well as I was hoping for (main issue is that the laser can’t get information fast enough to engrave at full speed) Furthermore I didn’t have a way to control the laser (laser is not in my room but remote; computer is in my room). Mobile phone to control the RPi is not exactly convenient so I wanted to do it different.
Best way is to directly control the laser and upload engraving tasks to the laser itself before starting. So I ordered an MKS DLC32 with wifi and touchscreen.
I connected everything. First I configured the laser to work with the touch screen. After doing that (and getting it to work, which means: moving in the desired direction with the controlbuttons and homing to the top right), I hooked it up to Lightburn (licenced) by wifi.
Again I need to change some settings but I just can’t get it to work. I did have the setup working with the RPi running Octoprint… So I used the parameters/settings from Octoprint as a start and tweak settings where needed but now I’m stuck.
My problem:
Homing to the top right works.
Coördinates at the top right are x-400 y-385 (minus coördinates!)
Coördinates at the LOWER left (sorry) (origin) are x0 y0
I can get the laser to move in the desired direction with the cursor arrows in Lightburn but as soon as I start a job (or draw a frame), the head wants to move to positive coördinates (so, to the left of the laserframe and over the front of the laserframe)
Of course I tried many things like changing the origin (but I want it lower left). I tried changing movement direction of X and Y, (and also changing the homing direction). But I just can’t get it to work.
I could move the end stops to the lower left corner but I put them top right so the laser head is out of the way when accessing the workspace. so no wires are in the way. (which makes me thinking… perhapse I should switch the entire laser front/back and left/right and move the end stops so they are on the other corner of the frame but still on the top right in the casing the laser stands in. But then the controller is not reachable but this one I’ll keep in mind)
But please, what setting am I missing or having wrong?
