Hi at all, i have a strange problem with my new controller RUIDA 6445S and i hope that you may help me. I mounted this controller on my laser machine and I have only one problem, when i turn on the machine the axes homing perfectly but when I press the buttons on the screen keyboard to position the laser head on the workpiece on the workplan it does not move or rather, the head would like to move in the opposite direction as if the workplan were mirrored obviously i checked the Dir and the Lmt Pol and the Key Pol and they are correct. I was 2 days trying to solve but nothing to do. I saw many Youtube videos and also searched in this forum hoping to find a solution, but nothing. I think it’s a controller problem but i’m not sure. I also made a Youtube video showing this error to understand better what is my problem:
May you give me a hand ?
Thanks in advance.
Best Regards

Hi, thanks for reply… i don’t have backup because my previous controller was a M2 Nano… this is a replacement upgrade… and about the after restart… my machine does the homing perfectly but the problem is after, anyway the values after restart are X:0 Y:0 z:3000 (i don’t have at the moment the stepper motor for Z)… if you take a look at my video linked in my first message you can see perfectly which is my strange problem… in this video there is all … the error situation, the parameters and all you need to search to understand.
Thanks
Hi Jack, the keypad directions works already right, in fact if i restart without to reset the axes and the laser head stay in the center or in any position of the workplan i can move it without problem up/down and left/right in correct way, the problem issues after homing like you can see in my video.
Regards.

Hi , thanks for reply… Like i wrote before the keying works fine both panel and RDworks the problem issues AFTER homing… in the panel show X:0 Y:0 Z:3000 and then the homing run correctly. After homing if i want move the axis is not possibles, in facts every movements go ONLY in reverse and then impossible because the head slam on the limiters… But if i stop the homing procedure after a reset with the Stop button, i can move in all direction the axis normally… this is the problem…
Thanks
You are intending to operate in quadrant IV. Home in the rear left. Since you can force it to lose steps in the X and Y directions it would indicate that the controller thinks its in quadrant II. Or that ‘home’ is in the front right.
The controller can only deal with positive integers. It will not allow you to force it out of bounds if it’s configured properly.
Off hand, not sure what to change. Never had this issue. I will google it…
Thanks Jack, you have hit exactly the problem , and never i had this issue too , for this reason i asked in the forum with the hope that someone could be help me, now i must think that the problem is the controller… or maybe the firmware ? my firmware is rdc-v26.01.13 because my controller is 6445S … if i use a firmware of 6445G you think that works ? Could be useful to back at the factory parameter ? Anyway thanks so much for your support… if you find something let me know.
I don’t know what the answer its. I’m sure it’s configuration. I’ve seen these with it homing in the front right and both back corners, so there is something we don’t know about how to change that.
Hoping one of the Lightburn wizards would have an answer.
It might be as simple is reversing ‘everything’, which would flip quadrants, but I don’t really know. The thought is that there are a couple of bits to change motor direction. If there are two settings that’s 3 different configuration modes. Maybe the combination you are using indicates to the controller which quadrant it’s running in.
It has to be configurable.
This is my early factory configuration. Maybe if you examine the the details it might help you find an anomaly. You could probably load it, but we have different machines and that wouldn’t really tell you much unless it worked afterwords. Motors are wired up different and all kinds of other issues creep up.
He’s very knowledgeable and has worked with these controller. He does have a support service, but you might just drop him a line and see if he can help. I’ve bought him a few cups of coffee for his assistance in the past.
Hi Jack, i really appreciate your interest in helping me to solve the problem. I will try to take a look at your file and we will see, in the meantime I have been in contact with Matt since yesterday and also this morning via videochat, we have done a lot of tests and following this, having not had positive results, he has consulted his contacts with RUIDA and now they send me a different firmware for my controller (6445S). They also confirmed that I cannot use the 6445G firmware because they are incompatible (this info if it should be useful to someone else) and if after this update the problem is not solved then I have to send the controller back for its replacement.
P.S. He told me that know you when i told him that you hit my problem…
Hi Jack, it cost me 6 coffees up to now , anyway, he is a really kind and scrupulous person.He too was surprised by this type of problem, in fact he also told me that it never happened to him.
Anyway, tomorrow he sends me the firmware and let’s see if I solve it otherwise i will send the controller back… and he advised me if possible to take the G version which is more widespread. I will report here any ending.
Regards
Giuseppe
you can change the motor direction by swapping the wires on your stepper controller witch will be a better option for you.You might need to change the “Dir polarity” if the image is left to right or inverted. I have done a lot of upgrades from Leetro to Ruida controllers and found that changing the keypad direction change to be tricky sometimes. So I try to keep the direction standard to the original settings as a service Technician.
Hi Gerard , thanks to reply, I did all the test like you suggest and also many other with Matt from MW Laser that is a very expert about it and also he has the direct contact with Ruida technicians. Together with them we couldn’t solve the problem. I’m waiting that they send me a different firmware like a last try. After that I must send back the controller.

Hi Guiseppe,
I have a 6445G that I am right now installing on my TS 4060 (BlueWhit)e over the last days and I had exactly the same problem. It drove me crazy.
What I deducted is that although it is a LeftTop machine and it seems to recognize that, after homing (going to left top and respecting the limit switches correctly) it thinks it is a RightBottom layout thus only wanting to go Left and Up from the homing position.
I got it to work but I am afraid I do not know what exactly I changed to solve this issue. I was solving a lot of issues at the same time by trial and error… but I felt it had to do with mixing up the motor direction and the keypad direction. At least I did not change any of the wiring.
I have attached screenshots of my settings, maybe you can see something that might help.
Good luck!
ps I have some other issues left so I assume there might be settings in there that are not good to copy ;-))
