General Mach Discussion / Change Wiring

« on: February 04, 2017, 01:58:44 PM »

My setup with the G540 is all complete and works fine but the motors direction is not the way I wanted. Like when I press the page UP keyboard button the Z axis goes down. I know I can change the Active Low from green to red or from red to green or perhaps from the Homing / Limits page click on the Reverse column? 

It’s also easy for me to switch the motor wiring but I don’t know which pair. From the attached Keling wiring schematic which pair of wires will change the motor direction?

Power supply is ok, did you wire the motors according to instruction? did you double check the wiring?
Are any DIP switches on the motor controller and are they set up as per instructions?

I would say the stepper drive or the the breakout board are not configured properly or the motor is not wired properly . Have you followed any instructions how to configure them?

....... It would be clear that the XML profile provided by Gecko sets up the input and output pins for their G540 drive.
They cannot know the steps/per value, or the velocity and acceleration values for your machine or any other machine.
Cheers,

I understand what you are saying Peter and for the fairness of all I still say that Gecko should have put a note somewhere in their Manual to say that in their XML the “Steps per” is only just a number and the user should establish their own value.

Let’s say I’m a guy who uses his mill for x number of years and one day I decide to use the G540 and since they provide an XML I say well Gecko is a big name might as well use their XML. I see the 20000 in their XML and I say well this number does not make any sense but since it’s provided by Gecko they must know something I don’t know or this number is something special for the G540. This scenario can happen to anyone

Another mistake on the same XML under Ports & Pins / Motor Outputs, Spindle line, the Step Port is 0. That should be 1 otherwise no PWM signal is generated (BTW I found this from another forum and it works for me)

I value the Gecko products and your knowledge Peter but that’s the way I see it and this post is not intended to blame anyone rather to state my experience and perhaps help someone.

I understand Gerry, thanks however perhaps Gecko should have put a note somewhere stating the 20000 may not be applicable to all users. I spent more than a day trying to configure my 4 motors to run smooth because I thought if Gecko says to use 20000 they must be right

My mistake Peter, 5080 is correct

Thanks

Thanks guys for the answers and BTW I use inches despite that my ballscrews are metric.

I wonder why Gecko uses 20000 since not all users will have a 10mm pitch ballscrews and although I do have 10mm ballscrews I have to use 4064 as Steps per

General Mach Discussion / G540 Steps Per

« on: January 28, 2017, 11:31:24 AM »

I got a new G540 and using the .XML from Gecko (540BVFD) the steps per setting is 20000 which makes my motor running very rough. Using the Mach3 “Set Steps per unit” on the Settings tab it gives me a steps per of 4002 which is pretty close to what I get with my calculations assuming a 1/8 microstepping. (my cals: 200 x 8 x 2.54 = 4064 with 10mm Lead ball screws)

What microsteps the G540 is using and can I change them?

That's news to me, I got mine almost instantly

Where did you buy it from?

Maybe you dont have a registered copy of Mach3?
