Dear All, I try to engraving this tap, Z axis seem not drop down. and the hole is small because I set it to 125MM and 9MM deep. Please help. THX! Attachment 241398 Attachment 241390Attachment 241394

If you have it set to zero at the top of the material, it should cut to 9mm depth. Outta my comfort zone with mm's, but what happens when it starts cutting? Does it rise up and do the toolpath? If so, then your axis is reversed.

[newnew005]

I sure Z axis has not reversed. I set the diameter of circle is 125MM and 9mm deep but it mill the little 5mm hole and 5mm deep.

Have you read the photo of setting, anything wrong? THX!

[LeeWay]

I looked at the images. I don't see anything jumping out. I think there should be another screen that tells you the overall size the machine will be cutting. That one is missing. Have you calibrated the machine?

I try the little tap of testing that is OK. I upload the 11.RAR (TAP) in my first post, would you like read it? THX!

[LeeWay]

I am unable to open that file.

your gcode is in inches, is your controller in metric?
either put a g20 at the beginning of your file, or pick a metric postprocessor.

[newnew005]

Yes, I am using Metric with Vcarve.

[alan_3301]

well your picking an inch postprocessor when you output to gcode, you needs to choose mm's

- - - Updated - - -

and it's weird that it doesnt add g20 or g21 so the controller knows what units it is dealing with. maybe that is a known vcarve problem.

[newnew005]

Dear Alan,

I already choose the metric in the Vcarve. you can see the pics in my first post. THX!

[alan_3301]

when you save the toolpath, it should give you an option to pick a post-processor.
This is different than the material setup or whatever that you set your units with.
It is clear is is outputting in inches if you look at your tap file.

T1M6
G17
G0Z0.7874
G0X0.0000Y0.0000S12000M3
G0X-0.2727Y-2.3712Z0.1575
G1Z-0.3543F47.2

Your controller is assuming the gcode is in mm, so it is only plunging to 0.3543 mm.
0.3543 inches = 9mm which is your set cut depth.

What post are you using? That doesn't look like typical code from V Carve Pro??

[newnew005]

Dear All,

thank you for your reply. I only choose the G code and don't know that has another choose in SAVE. I'll test it later. THX!!

[newnew005]

Thank you, I understand now. THX!

[newnew005]

Alan,
Would you like tell me, what program can read tap to gcode. THX!

[LeeWay]

You can read a tap file or Gcode file with notepad or any text editor.
