Tabs not cutting

Vcarvepro. Vectric post processor. Masso is not raising for tabs. Can anyone shed some light on this? My older machine cut the nicely. Thanks Gary

Hi Gary what post processor are you using and what version of vcarve?

I have been running the latest version iv vcarve pro with Masso Arcs post processor without any problems with tabs. Have you installed the correct post processor into vectric as there are specific versions for each version of vcarve

Cheers Steve

Hey Steve... I'm out of the shop for the day so no computer or cnc. I run the latest version of vcpro but I'll need to check the pp also. So I'll have to get back to you on that. Which one are you using? I must be using the wrong one. I'm very new to masso but with help from the forum I'm finally running toolpaths good except for the tabs. I'll post again in the morning.

Gary,

Upload the failing Gcode file so we can have a look at it, to determine if the fault is in the code or MASSO.

Regards,

Arie.

Gary,

Had a look at the file and I can see that there are several tabs in both inside & outside profile cuts and they vary in length between 5mm to 19mm but are only 1mm high!!

1mm doesn't leave much room for error in material thickness, Z axis zeroing.

You haven't stated what material you are cutting, but if it is wood / ply I would be aiming for a tab height of about 3 to 5mm (0.1 to 0.2 inches not 0.0394)

Regards,

Arie.

PS. Now I'm off to bed.

Hi Gary,

Just on a different topic you probably found that while cutting your project the machine did not move as smoothly as you might like. This is because your Gcode is made up of nothing but straight lines.

Once you have finished your toolpath editing, convert the drawing to circular arcs in your Vectric software before outputting your Gcode.

This will create a much smaller file that runs smoothly for you and gives you a better finish as well.

Cheers Peter

Good morning, Peter. I did not know that!! I will take care of that today. Masso is running extremely well as I learn more about it. BTW, I'm in the US, North Carolina to be exact. I shipped one of my pieces to a woman in NZ recently. The world is small indeed. Thank you!! Gary

It is indeed a small work Gary and getting smaller all the time.

Compare the files and I think you will find an improvement. If you give them a dummy run one after the other I'm sure you will see a difference in smoothness. Let us know what you think and if it makes a difference.

Cheers Peter

Peter, it did make a significant difference. I had noticed some jerky motion at various times and it runs noticeably smoother now. Thank you for pointing that out as I likely would not have picked up on the problem had you not pointed it out to me. Gary

So, after multiple test cuts in 3/4" plywood, I think I'm ready to cut that toolpath in figured bubinga. I'll see how it goes. Gary

Oops, another problem. I've noticed when the toolpath is on the monitor, what would be the top gets cut on the bottom. Same with the left and right, they get flipped. Today I carved text that carved backwards, like a mirror image. The tool change was also backwards. Instead of raising the bit it plunged into the table. Help would be appreciated. Thanks, Gary

Gary,

Where is the Machine origin (XYZ zero) when standing in front of it? Normally front left corner.

What direction is positive on X & Y ( left to right, front to back)? Left hand rule - thumb up = Z, index away from you =Y and middle to right = X and all pointing in positive direction.

It seems to me you have the machine reversed to Vcarve setup.
The tool change was also backwards. Instead of raising the bit it plunged into the table.

Could be setup error, what is your tool change setup?

Arie.

My 0 is right front. So the left hand rule my x is reversed. I used the right front because my x homing switch was on the right from my old installation. I used the tool change for the first time and it plunged instead of raising. Gary

Gary,

Easy fixed, in the Homing setup screen set X axis offset to the width of your X axis, this will tell MASSO that when it homes the X axis that it is positioned to the right of your machine origin. Be careful that your X axis settings match your homing settings, or you'll get soft limit errors when homing.
I used the tool change for the first time and it plunged instead of raising.

Again what is the settings of your tool change position?

Regards,

Arie.

Thanks Arie!! I didn't see your last post in time but I reversed the x axis and installed a homing switch on the left side. Toolpath carved correctly, asked for a tool change, touched off, and finished the toolpath correctly. I'm good to go. Thanks again, Gary
