Resuming Job Problem

Good day,

Anyone encountered this problem with their masso controller and any suggestions for the fix.

I've done a test run and tried to stop in the middle of a job, then i manually stop the spindle and trigger home for the cnc.

Ctrl + J to resume and set the last line i wanna start then click run. The Z then goes down very deep then travels to X and Y position, when the spindle reached the X and Y, that's the only time it goes up then position itself on the actual Z.

Hoping to get a fix suggestions on this soon. Thanks ?

Hi EONDODGE

When you do the CTRL + J and enter your line number Masso calculates where it will move too and the first move it makes is to move the Z axis the Machine coordinate Z zero.

If your Machine coordinated Z zero is at the bottom of the Z axis then cutter will start moving at this low position and then move to the final height when you start cutting. If you look on the screen capture below you can see that the ultimate Z position is 50.816mm lower than the Z zero position. you can also see that the actual position before I start the resume is -54.803mm so we can see that the axis will rise about 54mm move to the location then descend 53mm.

If your Z axis home switch is low on your axis you can fix this issue without moving the switch by changing the Z axis home position.

If your not sure take a screen capture of the Resume as I have and post it here. Pressing the print Screen button on your keyboard will put a screen capture on our USB drive which you can post.

I you need to post a GCode file just Zip it and you can post the Zip file no problem.

Hope this helps

Cheers

Peter

Hi Peter,

Thank you for your reply. I think the Z is now ok, but not the X and Y.

Please check the attached for the code and my machine XYZ zero position. Sorry for pasting it here while ago.

On the last job I've done, i needed to do emergency stop in the middle, it stopped at line 122444. I triggered home, then reposition to X - zero, Y - zero and Z - 10mm. Then, I do the ctrl+J and set the line start to 122400. When I click run, the spindle position went very far from my workpiece so i stopped it immediately. I tried to resume again from the home position(Same XYZ zero position), but still didn't hit my workpiece. I also tried to zero the X and Y at home position then resume but still the same, it didn't hit my work piece back.

I'm using vcarve pro and saving it as "Mach2/3 ATC Arcs (mm) (*.txt)", Isn't it with the post processor file i used? Can you suggest another post processor file i can use? Thank you.

Hi EONDODGE

I had a look at your file and see it its made up of nothing but short lines. This will cause very inefficient machining and if you hadn't mentioned you had used the Mach3 ATC Arcs post processor I would have said you used another Post processor. There isn't an arc in the entire file even though there is a circle in the center. How did you draw project you are machining? Did you do it on VCarve or another program?

Have a look in the Post Processor page for Vectric and choose the Masso Post processor that suits your version of VCarve Pro. If you are using version 7 or 7.5 please let me know and I will write one for you. If your not sure how to install it let me now and I will talk you through it.

https://www.masso.com.au/masso-documentation/?section=vectric-vcarve-and-vectric-aspire

When it comes to resuming you could not restart from line 122400 because there are only 12430 lines in the entire file. The line numbers you read in the file are in multiples of 10 and there are other lines in the file without numbers. It should have told you that it couldn't find the line.

When I did a resume on line 12240 and press CRTL + S the machine first rose to Z zero then moved across in the X axis and stopped. I press CRTL + S again and the axis moves in the Y direction and stops above the work. I press CRTL + S again and it starts cutting. If you haven't turned the machine of it should remember the X, Y & Z offsets and homing should bring everything right in case you lost your working coordinate position due to some issue. If you want to manually reset X,Y & Z zero it after you have homed the machine but before you start the Resume. It sounds like you are doing it right from what i read.

Could you please post your VCarve Pro file (only if you are happy too do so) and I will have a look at it and see why it is made up of tiny lines and we can go from there. Once it is outputting arcs the file will be much much smaller and cut a lot smoother. You will need to zip it to post here.

Cheers

Hi Peter,

Thank you for your help, I appreciate it. However, I still can't use the resume job function right now and still trying to tweak the settings to make it usable on my side.

The file i'm using is auto generated by vcarve. I don't have a wide knowledge in gcode programming to edit it.

For your reference, i've attached the vcarve file here. My z axis settings and .nc file using Masso ATC Arcs (mm) as post processor. I've downloaded the 8.5 Version post processor but i'm using VCarve Pro Version 7.514 (Build 1978.1567.170). Hope this would help.

On my last test run, I think the Z axis has an invert direction when i use resume job function coz it goes deep first then slowly going up as the spindle is moving to the workpiece position. Here's the video, it's too large to upload here so i put it in you tube:

I also wonder why the X and Y skip or passes the workpiece and goes very far then goes back to the workpiece position again. Is there a way that x and y will get straight to the workpiece position directly?

Hi EONDODGE

Let me start by saying a big thank you for the information and video. It sure makes it easier to understand what you are experiencing when I can see it and can run it myself. Thanks also for the screen dumps.

I ran your file and the Resume worked fine for me though I can see the strange behavior you are experiencing.

What did you do to Stop Masso running?

It looked like you homed the machine after it stopped and before resuming. Please confirm.

What version software is Masso running. Just open the F1 screen and it will be in the bottom left hand corner. Just do a screen dump if you like.
?Could you please send a copy of your MASSO_Settings.htg file for your machine.

Just go to the F1 screen then under Save & Load Calibration settings click [Save to File]

This will save your machines settings to the USB stick.








On a completely different matter

I looked at your drawing and it looks fine and the Gcode looks good as well. It was the previous Gcode file that had me scratching my head.

I can create a Version 7.5 Post processor for you if you can send me 2 files from your PostP folder. I'm using the standard Mach3 Post processors as the basis for the Masso ones and haven't been able to find them for version 7.5 . I would be grateful if you could send me the files listed below and I can make you some Masso post processors specific for your version of VCarve. It is interesting that the V8.5 PP worked for you but there could be something unexpected lurking for the future so we are best to make a separate one for 7.5

Mach2_3_Arcs_mm.pp

Mach2_3_Arcs_inch.pp

Hi Peter,

I used the emergency button to stop the machine. After the e-stop, I homed the machine and from the home position, I do the Ctrl+J.

Attached the htg file and screenshot of the masso version software.

Hi EONDODGE

Thanks for the info. I will get you a version 7.5 PP before the weekend is out.

I was a bit suspicious of the version because the Jump to line was in a different place on the screen from mine.

Could I ask you to contact support and request the updated software version if you cannot find it on your PC. You should have received several updates since the one you are now running so it may be on your PC or in your spam folder. I'm concerned that given the age of your software it might have a bug in the Jump to line part of the software and it is causing you the problem. You will need to let them know your machines serial number. Sorry i don't have the ability to do this for you. Just use the Contact us at the top of the page.

The version you are looking for 3.40 or higher

Cheers

Peter

Hi EONDODGE

Started editing the Post processor files and realized I made a mistake and asked for the wrong files.

I should have asked for the Auto tool changer versions. So far everything looks the same between 7.5 & 8.5 but if you could send the ATC versions when you get a chance I will go through them and makes sure.

Mach2_3_ATC_Arcs_mm.pp

Mach2_3_ATC_Arcs_inch.pp

Sorry about that

Cheers

Peter
