SmartBOB controllers and dedicated accessories / Re: problem running G Code

« on: June 09, 2020, 07:50:37 PM »

Yes, jogging one inch in any direction will show 1 inch on the DRO as well as physically moving one inch. I tried jogging at 100% and that seemed OK too. So I tried running the GCode
G0Z0.5000
G0X1.0000
G0Y-1.0000
G0Z0.5000
G1X0.5000
G1Y-0.5000
and that seemed to work no problem. I then went to the original GCode and added a few new lines to match what I originally had so it was now
G0Z0.5000
G0X1.4023Y-1.5354Z0.4000
G0X1.0000
G0Y-1.0000
G0Z0.5000
G1X0.5000
G1Y-0.5000
and it seems moving more then one axis is what is causing it to start pulsing, so the line
G0X1.4023Y-1.5354Z0.4000
started causing the issue.

I've also attached the profile if that helps any.
Thank you.

SmartBOB controllers and dedicated accessories / problem running G Code

« on: June 05, 2020, 12:06:22 PM »

Hello, I have a 424 smart board attached to a 133 motherboard with g201x gecko drivers, and I've managed to get everything set up and running fine when I'm jogging the motors in Mach 4. The problem is as soon as I start to run something with G Code, I get this strange pulsing and the motors only move a fraction of what they are supposed to, and the pulsing won't stop until I cut the power to the 133. I tried reducing the speed and velocity of the motors, but no luck. Any thoughts what it might be?

So I removed the black and white wires and it is now jogging. Still not sure if it should connect somewhere else, but I'll take it as a success for now!

There is something I'm confused about which I'm finding probably means I'm doing it wrong. I have 6 coil nema 17 stepper motors. I'm 95% sure after much searching (I'd say 100% but I can't find the official manufactures documentation) that I have the correct A(yellow) A- (red) B(orange) B-(brown) wiring. What I'm not sure is where the center tap wires go, white between A and A- and black between B and B-. Since the 133 had 6 spots for wires I figured the black was ground, but now I'm not so sure. Do I just pull those out, do they go somewhere else, do I have it reversed?

OK, I really misunderstood that one, thank you for pointing that out.

So I plugged in the 407 then the cable for the 133. I turned everything on and connected the usb cable, then started up mack 4, everything connected and lit up as expected. I then clicked enable and the DS3 LED lights up on the 424 board. I then I clicked to jog the motors and no movement but the 133 started pulsing sending some signal to all 3 motors and the motors were no longer locked in place, I could manually move them. The pulsing won't stop until I cut the power to the 133, and then it would reset itself until I tried jogging the motors again.

I've attached an image of how I have it configured. I don't have the ribbon connected to the 133 motherboard connected to J6, but from what I can tell that's not correct. I tried moving it to J6 but it wouldn't connect when I started up mach 4 (the DS1 LED only stays red) and I can't connect the 407 board to the other connector.
As far as the LED's  DS2 lights up as soon as mach 4 is connected and DS3 lights up when I select enable in mach 4 but doesn't flicker when I'm jogging the motors.

OK, I see what you mean. Yes, when everything is powered down I can move the motors by hand, as soon as I power up the boards the motors lock in place, even before I start up mach 4. When I start up mach 4 the 424 breakout board goes from red to green showing it's connected. When I jog the motors the numbers change on the DRO but not the motors themselves. I'm including the machine.ini file.

Thanks,
Greg

OK after search around for the model of motor I found these specifications

- Model: SST43D2121
- Degree per Step: 1.8
- Degree Voltage: 4.0 v
- Amperage: 1.2A
- Resistance: 1.3 ohm
- Inductance: 3.6mH
- Holding Torque: 34.1 Ncm
- Number of Leads: 6

so I guess, according to this, a holding torque, still not sure how that effects anything.

Thank you for your reply! I did change the set/dir to swapped and I do not have anything connected to the motor disable connector (as is recommended). I do not believe I have holding torque on the motors but I'm not sure exactly what that is. Still nothing though.

I attached my profile if that helps.

SmartBOB controllers and dedicated accessories / setting up 424 with 133 and 407

I just got my whole system set up with a 424 smart board attached to a 133 motherboard with g201x gecko drivers connected to three motors (sst43d2121 if that makes a difference). I also have a 407 spindle controller connected to my spindle. I got Mach 4 and all the drivers installed, when I start it up everything thing show that it connects correctly but I can't get any of the motors or the spindle to turn. I've gone through all the settings, several don't make sense to me. Can anyone help with my initial setup? Thanks in advanced.
