Mach4 General Discussion / Re: Reference all axes (Home) on a machine without limit switches

« on: July 05, 2017, 03:07:48 AM »

Hi,
when you say the DROs do not reset are they configured to display work co-ords or machine co-ords?.

When you have 'homed in place' have a look on the diagnostics tab and see what the machine co-ords are.

Craig

1. Machine coordinates.
2. Haven't done that, I will check later today.

It might be useful to know that this function worked well in Mach3 with the Mach3  PoKeys plugin. The main difference between Mach3 and Mach4 in this respect is the option to reset the machine coordinates at the homing operation or not. This option is not to my knowledge present with Mach4.

Still haven't solved the home-in-place issue. When hitting the Reference all axes (home) button the DRO is not reset to Zero for all enabled axes. The DRO LEDs however, almost always turn green. In a few instances it won't. Often, there is a error message in the history line stating

Code: [Select]

Motion steps overflow (9600) - check motor speed parameters (0 -> 9600  / incr: 0) - move 1018673
Motion steps overflow (-9600) - check motor speed parameters (9600 -> 0  / incr: 0) - move 1018674What does this mean exatcly?

I've logged the events occurring when the home button is pressed. These are as follows:

Mach4 General Discussion / Re: Reference all axes (Home) on a machine without limit switches

« on: May 31, 2017, 03:27:24 AM »

Still no luck. I have a CNC3040T which has 4 axes and a PoKeys57db25USB external motion controller. The A axis is a rotary type which of course cannot have a home switch.
I use the wx4 screen set and have disabled the A axis because I don't use it for the moment.

- The motor tuning tab, Motor3 is uncecked
- The Axis mapping tab has only X, Y and Z mapped.
- The Homing/softlimits tab only the X, Y and Z is set to Home in place. The soft limits are set to within the travel of the table and stroke of the Z axis (0...270, 0...370, -55...0 all in mm).
- The input signals tab only has E-Stop and Probe inputs defined and mapped
- The output signals only has Enable signals mapped to Motor 0, 1 and 2

When I klick the "ref all" button, whilst wtching the machine coords, the DRO leds turns green but DOES NO reset to 0.000 for the enabled axes X, Y and Z.
I get an error rmessage that says "Step pulse overflow" with numbers I don't understand.

Maybe this can shed some light over things for you experts out there.

Thanks in advance, /Thom

Hi,
amongst the things I do with my mill is isolation routing of circuit boards. My success has improved considerably by using Autoleveller
software from the UK, any Google search will find it. I liked it that much I paid 20 quid for the subscription.

Craig

Hi, I'll check it out. Thanks.

In Gothenburg. I have the "small" Pokeys57db25 motion controller so it has very limited capabilities. That's why I invested in a Vista pendant not to take focus away from what I want to do. In the future however, I just might get myself one of the fullsize PoKeys controllers to get more degrees of freedom. Rigth now I'm set on geting the CNC router to machine some PCBs for me.

« on: May 30, 2017, 07:27:15 AM »

Additional info: When i power-cycle the controller/pokeys motion controller and restart Mach4 it starts with machine coordinates at 0, 0, 0. That seems to be the only way right now to do the referencing. Otherwise, the machine, Pokeys 57DB25 and Mach4 works fine and runs a Fusion360 .tap file smooth as a babys arse. Just this button home referencing does not work as expected. I interpret this as I must have homing/limit switches setup to do a proper homing maneuvre. I'll try to setup and fake the three switches by pressing them by hand to see if that maybe will work. Maybe look at the lua code for that button too.

Hi, I chose the M1. Since I live in Sweden shipping and import duty adds about 50% to the cost.
But I'm going to save myself some time

« on: May 27, 2017, 07:23:20 AM »

When jogging to the "home" position and pressing the [Reference all] button, machine coordinates does not reset to zero. Why?

In homing/Linits the [In place] is checked. All limit switches are disabled in my PoKeys plug-in and in Mach config.
In Mach3 there was an "Auto Zero" option to make this happen but this is not present in Mach4.

Any suggestions?

A better alternative for sure. Which type pendant did you buy?
(I was looking at the M1 or M2 as possible candidates but there seems no plugin for M2 for Mach4)
