Problem description

Hello, I have a CNC 3018, and I keep getting "error while processing response". On laptop i run ugs platform and I don't get the error it just stops moving, I have to disconnect the usb to regain control. On pc i run ugs 64 and I get the error and sometimes it stops, but not so often.

I have tried Candle and LiteFire for laser, same problem, it just stops.

I grounded my laptop on usb, I grounded cnc frame and spindle supply. Same problem.. I reinstalled usb driver CH3xx.

I have read all the forums I found, still no solution.

What can I do to fix this, any suggestions or ideas are more then welcome.

My config is:

UGS Platform v2 nightly build apr 23 2019 windows 10 86 on laptop windows 10 64 on pc

It sounds like you also suspect electromagnetic interference as you mentioned the grounding. Just make sure you have not created any ground loops which would act as antennas.

I would start by checking the usb cable and make sure it is thick and shielded.

Does this occur if you do not run the spindle or stepper motor drivers?

de3tri commented 4 years ago

I have only 2 cables, it's 1-1.2 m long.. both of them. At this moment it's connected to PC and it's not grounded in any way, but how is it a ground loop that acts like a antenna? Yes it is happening also while stationary, as you see I have posted Idle mpos..

khturnings commented 4 years ago

I have had a similar issue, I believe I have resolved it in 2 ways -

I replaced my cheap Arduino which had a CH3XX usb driver chip with one that has ATMEGA16U2 chip - https://www.ebay.co.uk/itm/173653258248 This was a partial fix i.e. improved performance but still had some dropouts and freezes
I replaced my cheap 2m usb cable with a good quality 3m usb cable which also has a built in signal repeater and this seems to have fixed my issues. But I have yet to test on a long running job.

Maybe this will help you de3tri

de3tri commented 4 years ago

I'v read about chip 16u2, if has the last firmware it wont make any more problems, I was looking where to buy one in my country.. What is so strange to my is that weird characters in the error..

abdset commented 4 years ago

Are you using a CNC pendant connected somewhere on the controller ? The manual say dont connect USB to the PC and use pendant at the same time. I dont have that machine but i gess they are sharing the same port. Also you may:

Check the baudrate at USG platform connection section (top left on the screen) set it to 115200.
Have you choosed the right controller firmware on UGS Platform ? (GRBL or smouthieware or tinyG or so ..) according to your machine. Most people are using GRBL.
Try to find the micro-controller bootloader file on the net and reflash it, some people get their connection issues fixed by doing it.

de3tri commented 4 years ago

I'm not using a CNC pendant, I don't have one.. Port it's set good, 115200. I just ordered a new Arduino uno with chip 16u2 and drivers DRV8825, I hope they work better. How important it's a cooling fan to blow on the shield?

abdset commented 4 years ago

DRV8825 has a feature that will cut it from power when its too hot before it gets damaged. This mean a quick job will be fine without a fan but longer job will take time and need a fan to cool them down. You also need to put heatsinks. They are a very good drivers, i'm stressing them a lot and never have issues. Please let us know what did fix your issue when done. We would like to help others if needed. Until you get your new parts, you could try to flash the bootloader and see how it goes, if its a succes you will have two working controllers.

de3tri commented 4 years ago

So my new Arduino uno with drv8825 had arrived and I installed them, they work like a charm, no errors, no problems so far, and if until now my max speed was 1200 mm/min (at 1500mm would freeze) now I work with it at 1500-1800mm/min, (at 2500 it freezes).

Now problem nr2, to connect the laser to the shield, can I use a different power supply and use only one cable TTL or do I need a step down dc-dc so the GND is common ? The "manual/internet" says that Z+ is now tll, and If I measure Z+ and GND it is, if I set laser power to 100% I have 5V, as expected.. but so does Z-, Y,X, SPNEN,SPDDR etc and all of the pins ... and that is werid.

abdset commented 4 years ago

For the feedrate, if you have more amps and volts for your motors you can then reach higher speed. I am using a laptop power supply whitch delivers 19 volts at 4.7 amps and my machine can reach 10000 mm/min without any issue. I use 7808 to pull down the voltage to 8 volts whitch i am using for the arduino uno (connected to its power plug), and 19 volts goes directly to the cnc shield for the motors.
I dont have experience with laser though, so i think you will need somebody else to help you with that. Wish you the best.

de3tri commented 4 years ago

My power supply is 24v, 4Amps, but as I was saying, with arduino nano and A4988 drivers my max speed was 1200mm/min, now it's much better. Why do you power aruduino uno? It's not connected via usb?

khturnings commented 4 years ago

@de3tri good you god things working smoothly. You can power via USB or independently.

For my machine I use 36v to power machine and an old ATX power supply to provide 12v for my laser. I also use the 5v rail to power some low powered laser crosshairs for aligning my router. I will look later at my Laser -> Arduino connections and post what they are.

abdset commented 4 years ago

No i'm not using usb on arduino, i have added ESP32 connected to arduino via RX/TX and have done a program that will allow me use my machine via bluetooth with joystick jogging feature. That's why i need to power the arduino (no usb cable connected to it).

breiler commented 4 years ago

Closing issue as it was resolved using a new arduino.
