I would have to look bur I think I had to remove the underscore from the $R so it would be present on every line. For G83 there were 2 variables that needed the underscore removed.  Again I'm guessing and would need to check.

Thanks. For the record I did do a search and nothing came up. Must have screwed that up a little.

Done. Thank you!

I would like to send a copy of the new Mach4 post processor to a pal. Where are they stored on the hard drive?


So just change this

{$g82} {$_x} {$_y} {$_z} {$p} {$_r} {$_f}

To this?

{$g82} {$x} {$y} {$z} {$p} {$r} {$f}

Below is a little snippet of code generated by CamBam

The G81 and G83 lines read as

G81 X-0.4136 Y0.1305 Z-0.03 R0.025 F5.0
G81 X0.4139 Z-0.03

G83 X-0.4136 Y0.1305 Z-0.6 Q0.05 R0.025 F5.0
G83 X0.4139 Z-0.6

How do I make the post processor put in the complete line of code every time. Mach4 needs the complete line or it wont run the code. I'm sure the processor only puts on the line what variables have changed but now it needs to do it for every line weather it changed or not. See below changes.

G81 X-0.4136 Y0.1305 Z-0.03 R0.025 F5.0
G81 X0.4139 Y0.1305 Z-0.03 R0.025 F5.0

G83 X-0.4136 Y0.1305 Z-0.6 Q0.05 R0.025 F5.0
G83 X0.4139 Y0.1305 Z-0.6 Q0.05 R0.025 F5.0

CamBam help (General usage) / Re: Spiral drilling method?

Silly question but couldn't you just drill the holes and follow up with a reamer? The cutting forces would be straight down instead of side loading the router. Seems like it would be easier on the router. I don't own one so I'm just guessing. Depending on your collet setup you should be able to bite down on a letter "D" drill bit and then a 1/4 shanked reamer.


I'm sure it was not received that way. The reason for questioning is so that the steps can be recreated and get to the problem and get it fixed. I have been hovering this forum for many years and have never seen anyone treated disrespectful. I'm sure your report is appreciated will be taken seriously. This is a great bunch of people and work very hard to get any and all problems figured out. The line of questioning was just an attempt to gather any and all information to isolate the problem in a speedy fashion.

How oval is it? Is it a few thousands off or it it half as wide as it is tall?

Is the machine calibrated? By that have you setup the steps per inch recently and was it checked/ confirmed to be good?

Is there a worn out ball nut or balls giving too much back lash?

Need some more details.

When you opened the DXF file in cambam was it the correct size. Could it be that you are opening a metric file and cambam is set up for inches? Upload the dxf file and i'll see what happens when I open it.

Just to be clear the lathe options that are in Cambam work very well. I have used them many times over the years and it has all gone very good.

It probably could but would be a lot of work. I have been doing 95% of my lathe code in mach4 editor by hand. Makes it easy to test that way. I just cut and paste the back and fourths and edit the x position. Doesn't take long. Just would be a nice option and a huge time saver when able to be used.

Yes post processors can be edited to change the output or geode. I know nothing about plasma cutters or it required geode so I can't  help with specifics bur I'm sure cambam could do it if you are willing to do a little research.

I typically step up until I notice missed steps and then back off about 20 percent. Also look at acceleration if it's available. You might be able to go the current speed, you might just be trying to get to that speed to quickly. Ramping up to the current speed slower could also prevent losing steps.

I'm not sure you can read the current position.  I typically set a stopping point. When I do a sparkplug base first operation I press cycle start and the lathe machines everything below the hex and then parks out of the way so I can run the threads with a tail stock die. Then I cycle start again and everything  above the hex is machined and parted off. then the lathe parks again so I can loosen the chuck and advance the stock until it touches the cutter. That way the stock is exactly where it needs to be to machine the next part.

Those parking spots are part of the code and precise positions. You need to figure out where you want that position to be and set the xy and z in the footer as code commands. You can also add other code commands and they should be added to the end of your program.

Click on "Machining" and take a look at the " custom file footer" I think you might be able to enter those 3 lines of code in there and they will be added to your gcode file when you post the code.
