ruida rdc6442g stuck on 10000mm x and y axis

[Michaelsbram Bramblett]

Looking for help with ruida 6442g controller issue for 55w co2 laser. I believe I reset manufacture settings while trying to fix an alignment issue... My x and y axis are stuck on 10000mm. Every time I turn machine on the laser head will bang against side and I have to press ESC to stop. The company I purchased the machine from sent me screen shots of vendor and user settings. I've input them using rdworks and lightburn with no change. With both programs, I can read machine settings, manually change (according to screen shots) and write to machine. When I read again, settings ARE CHANGED but x and y still read 10000mm on keypad on machine. The only thing I have not tried yet is to go this process by loading a file with the correct settings instead of manually. Any help with this is greatly appreciated as my machine has been down for going on 2 weeks. I purchased machine from OM Tech 6 months ago and it was working great until last week. I changed the rising edge setting in an effort to fix an alignment issue which didn't fix my problem. I then contacted om tech and was instructed to reset settings. That is where my trouble started... I reset manufacture settings and default settings using CC8888 and HF8888. Every since then, x and y have been stuck on 10000mm. I've read several posts on forums that mention loading user and vendor settings fixed this same issue. However, this didn't work for me manually. Maybe using file would work?
Thanks!

It makes this if the axis are not correctly homed. They shouldn't bang and it should not be aborted with esc, if they work correctly.
So the first thing to make sure, is the head moving towards the endstops after powering on. If not then you have to set the machine home in the firmware (with rdworks, vendor settings, read, set correct pos. and write, restart machine).
Power off before reaching the endstop.
Second test would be manually setting the laser head away from the endstops and while powering on, simulating an endstop hit with a screwdriver.
If this works, your endstops should be correct and after a successfull initialisation the positions should be displayed correct after a new power on.
If it doesn't work, check the endstop wiring!
PS: Try not to crash the gantry while testing and tuning!

Currently, the laser head is front right and it move (bangs) front right at machine start up. So basically, I hear a noise (like its homing) for a few seconds then starts to bang front right if i dont hit esc or turn machine off. As I mentioned in post, when settings are changed and machine restarts... back to square one. I can read, change, write and restart machine and after restarting I hit esc or it will bang on sides and x and y are always at 10000mm. Should I power off machine before banging instead of hitting esc? Seems like whatever I do (I've tried changing a few settings, polarity etc..) but still ends up with 10000mm for x and y. Having no luck with getting backup settings file from Om tech (maybe theres a setting that I'm missing putting them in manually). This is frustrating!! Is it possible to reload firmware to controller or is writing vendor settings essentially the firmware? I can read the machine after changing and changes are correct. for example, 600 by 400mm change will show after reading but if you look on machine, still shows 10000mm.

pics are after start up. laser just keeps trying to move to front right. Also, laser does not move manually. Red (limit switches?) are on left of x axis and back right of y.

We always advise recording the Vendor settings first but I guess that ship has sunk? We have some Vendor files in the FAQ section, you could try one from a similar machine and if you are [it sounds like] in communication with the laser co. they should be able to send you the file. As a sidenote you can use Notepad++ to compare the files [with a free download] and change them off the machine. And as has been mentioned the 10000 readout is normal for a machine that has not homed correctly.

Thank you! I will look in FAQ section

Are the arrow buttons not working at all after hitting esc? The head should move in all directions.
If not, maybe a wire from the motor wiring came loose. Could you check the connection/wires between the control board and the motor drivers and the connection/wires from the motor drivers to the motors?

When pressing arrows, the laser head makes noise like its trying to move but not going anywhere (behave the same using rdworks, lightburn and on keypad)... Like its trying to move against gantry. However, up, down, right, and left behave the same (make noise but no movement). Should the laser head move freely when machine is on? It does not move at all, stuck in front right position like in pic above when machine is on. When off laser head moves freely on x and y axis.
connection wires seem to all be connected

Yes, the gantry should move with the arrows, even without homing.
Look at the video https://www.youtube.com/watch?v=X8iqgfy ... el=MWLaser , after around minute 14, check the step length to get the motor moving (don't change the dip switches).
After the motors are moving https://www.youtube.com/watch?v=PipeAxh ... el=MWLaser and https://www.youtube.com/watch?v=WS_Qkim ... el=MWLaser could help too!
This are my cfg settings, the z axis is not connected on my machine and just yesterday I upped from 500x300 to 505x314mm because there is enough room and I needed 500mm width

Thank you for the settings! I also received file from om tech today. I loaded settings via file and ALL IS GOOD, Back to normal! Comparing the settings from file and the settings you posted... There were only 2 differences.
1) The file had edge PMW rising edge checked for x axis only
2) Step length was 30.02245 for x (similar to yours) and before loading changes I was at 3.2 for step length on x (I believe this was my problem, you think?)

One more question... Regarding PMW rising edge, Did you uncheck this for a reason or was it already unchecked? Reason I asked... I had an issue several months ago where my stitching holes were getting off set on long runs. For example, I would cut 1mm diameter holes (5mm apart). If I cut a long run (say 40) in a line, several of them would be off set. I unchecked PMW rising and this fixed my issue. I don't know why but this fixed my issue at the time. I've made several cuts today and all looks normal but just wanted to see if this was something I should leave alone for now or if I should go ahead and change now to prevent my previous problem.

Thanks to everyone who replied on this post!
