Hello

Anyone know why I'm getting incomplete pocket cuts like this?

Yes, use a smaller step over   ; mostly 0.6 give a good result without "holes", but sometimes a small change to the step over can give a very different result depending of the shape, tool diam, etc

Hello

Nice ! 

I used a jpg file so that is why it is squiggly

To remove the stairs, if you're using the CamBam Bitmap object, you can set a smooth value.

If the picture has been digitized on another soft, you can smooth the stairs with the following plugin.

[when the tool number change between two machining operations]

Hello

First: your GCode must contain Tn M6 commands ; those commands are written by CamBam in the GCode when the tool number change between two machining operations (don't use 0 as tool number ; it disable toolchange)

ex: if the first mop use tool #4 and second mop with use tool #9, CamBam will write a T4 M6 before the first mop and a T9 M6 before the second mop ; if the tool number do not change between two mop, no Tn M6 will be written in the GCode.

So, you just need to take care that when a new tool is used for a machining operation, the tool number is different from the previous.

Be careful ; tools of different diameters must not share a same tool number ; if this is the case, CamBam will complain.

Second: The software that drive the machine must be set so it react to Tn M6 commands ... and it's software dependent ..

Ex, in Mach3 you can choose what the software must do when it encounter a Tn M6 (see picture)

- ignore toolchange

- stop and wait for manual toolchange.

- use an automatic toolchange macro (ATC)

after the tool has been changed, you must redo the Z 0 for the new tool.

What is you driving software ?

Was just seeing if Andy was monitoring the forum

Andy connects to the forum every day right now to kill the spam coming in the day, and I kill those who arrive at night LOL; I do not know if he has time to read the forum, but he probably looks at his private messages.

The license file is called "CamBamPro.lic" and is in the CamBam install folder.

If you can't retrieve this file, you must contact Andy Payne to get a new copy of your license file.

Currently I'm using the V 1.67 ...

Just tried the G73 ; work OK ... and on CamBam, you just need to change the G83 by a G73 in the GCode section of the PP ; do not change anything in the G83 macro itself ; then use the canned cycle as usual with a Peck distance value.

Never tested the G73 but it is interesting features ! , but they said "Rapid back out by the distance defined in the G73 Pullback DRO on the setting screen" ... but I can't see this dro anywhere in the screen ... I'll have a look in Machscreen to see if I can retrieve it ..

edit: OK, it's OEM DRO 91 .. and it is not present in the standard Mach3 screenset (1024.set)

Yep ; I just have a look on UCCNC from CNCdrive and it support G73 and G84 (page 64/65 on the PDF) ; the software is close to Mach3 (and is able to read a Mach3 config) but it works only with CNCdrive motion controller like UC100USB, UC400ETH, ... (that are also Mach3 compatible )

http://www.cncdrive.com/UCCNC/UCCNC_usersmanual.pdf

https://www.cncdrive.com/UCCNC.html

The software is very affordable (60$)

motion controllers compatible with UCCNC

I don't understand why there is 2 prices   .. ex on the AXBBE .. from 198$ to 347$ ... I don't see differents versions like 4axis / 6axis ... (the AXBBE can be used with up to 6 axis)

I may not have it setup right yet. 

No, this function is not supported by Mach3

[auto]

Hello

Not sure to understand the question  

If you want to V-engrave at the bottom of a pocket, it's like for other mop ; set stock surface to the bottom of the pocket as on the example. (take care to set target Depth to auto so the plugin take the tool diameter in account to avoid that it plunge further than the V)

a small video attached, this show how to redo the nose.

I think that once a closed loop is obtained, the hatch plugin could make this work.

Yes, and it is the same for pocket (I assume that you want to say "closed polyline ?")

I tried to draw a line in 3 spots to get it to close up. I could not get it to work.

Yes, it is not sufficient

Hello

Either case, I tried closing off areas with a line or an arc and had little luck joining everything together. I played with it for awhile and came to the conclusion there has got to be a better way.

Yes, it's a long job to do but I'm not sure that you can find something that can do the whole job automatically. In most case, digitizing a bitmap to get outlines needs some manual job to achieve a perfect job. (and your project is not a "difficult" case)

Filling the "black" areas has been done with this plugin (the hatch can be engraved)
