Mach4 General Discussion / Re: Pokeys57CNC and probing

« on: April 02, 2017, 01:15:08 PM »

Hi guys,

I have still problems with the probe function in Mach4
When I click on the measure button I get the error message "ERROR: No contact with probe"
When I click on the measure button with the probe grounded I get the error message "ERROR: Probe obstructed"

Did anyone solve this issue?

Regards,

Thom

Thom,

I know this thread is pretty old by now, but I messed around again today, downloaded latest Mach4 and latest plugin, but still can't use the "Touch" function in Mach4 :-(

Sometimes it would work, sometimes it drives through the plate (which luckily I keep in the air) and sometimes I get "Can't transition from RUNNING MDI to STOP" or something similar to those lines.

Just too unreliable, so I also use the same script you use at the moment and also created similar ones to probe X and Y.

It is a real shame the builtin Touch function is unusable, at least for us with Pokeys controllers.

check this post from DazTheGas .. works perfectly for me (on pokeys), but I know he also runs ESS: http://www.machsupport.com/forum/index.php/topic,31367.msg217701.html#msg217701

Hi Stuart,

Same here, probing screen is unusable for me or I just don't know how to use it . I mainly only the use an auto z zero probe, so created a button on the main screen with a script found somewhere on this forum as the new "touch" module also does not work for me.

Anyway, the script works for me, so I am happy just to use that for now.

installed latest 3124, latest firmware 4.2.5 and latest plugin, but still struggling with probing. not sure if it's mach4 issue or not. on the "touch off" module, when I click on the button to find Z, it goes down, touches and retracts as expected. Do it again, then as soon as it touches the plate, it stops dead with error" Cannot transition from MDI to Stop" and disables the pulse engine. When I enable again, click on find Z again, it keeps on feeding down, driving into the touch plate (even when it says probe input is Active) ... just too unpredictable.

I am just going to go creating my own button with an auto z script.

Update: we have been using 3112, which is the latest dev version with SDK, but have now tested 3124 also.

If you experience any problems with probing, I suggest upgrading the firmware to the latest 4.2.5 version and execute 'Device > Clear settings in device' from PoKeys configuration application to restore the device to factory defaults. Except for the IP address configuration and PoNET (kbd48CNC) devices discovery, all Mach4-related settings should be automatically be configured by the plugin on the first start.

Thanks, going to try this evening.

The external pull-up on v1.2 boards is not required.

Are you able to replicate the issue with probing? We are testing it now and can't make it fail.

Thanks, i wonder if my pull-up is then causing issues ?

Also, are you using the touchoff module in the latest mach4 dev build available here ? (http://www.machsupport.com/forum/index.php/topic,27039.msg227697.html#msg227697)

Hi, guys

We haven't been checking the Mach4-related forums...

Can you please let us know which Mach4 plugin version you have been having problems with probing? We fix some early bugs a while ago and are eager to know whether anybody is still having issues with it.

* early PoKeys57CNC boards (v1.0 and v1.1) required an external pull-up resistor to be added to the probing input due to a hardware bug.
* pin 17 should be selected as probing input with invert option enabled. This should also work with simple contact-based probes.

Regards,
Matevž, PoLabs

So we do not need an external pull-up with v1.2 boards ? Will it make any difference if I have a pull-up on the v1.2 board ?

I am not 100% sure if it is Mach4 or Pokeys .. probe is connected to pin 17 and whenever I touch the touchplate, the "probe led" in Mach4 lights up. I created my own script for my z-zero touch probe and it seems to work consistently, it's just the new touch module in mach4 that seems to have some issues.

before i tested, I did download the latest dev build of Mach4 and the latest mach4 plugin as well.

i get the same with my pokeys ... just does not work .. although sometimes it does, you just never know. i only really need auto z for the machining I do, so made my own button with a script I found on the forum. the new touch module in the pre-release also does not work properly .. at least for me.

also have weird issues with the new "touch" module. It is just not consistent. Sometimes it works, other times it just keeps driving through the touch plate. Clicking the X finder, my Z axis moves. Sometimes it stops dead when it touches the probe contact and does not retract with an error "Cannot transition from MDI to stop" or something like that. Just all over the place.

I am sure Mach4 has been in development for quite some time now, why does all these bugs still exist? I never had these issues with Mach3. Disappointing really. I never know when I am going to break a tool or drive a hole in my touch plate.

I will have to go back to my own scripts for now, at least they worked relatively well, although not completely without issues either.

Mach4 General Discussion / MDI button non responsive

« on: June 05, 2016, 01:45:12 AM »

Hi Guys,

If I start up Mach4, put say, G0 X0Y0 in the MDI box and hit cycle start, it works.

Once I run a script that I assigned to a button (for example, auto z tool) and go back to the MDI box and put something in there, nothing happens. I just get "Do MDI 1" in the Last Error box, but the machine does nothing ?

Any ideas ?

Thanks !
