Peck drilling problem
« on: November 23, 2005, 09:09:22 PM »
I am in the process of building a vacuum forming machine and want to drill a 1000 odd holes in the platform.
My problem is that while I have made the code for this, and the code says to retract the drill 2mm b4 moving to the next hole, insted it retracts the drill 50 mm each time. At first I thought it might be a safe Z issue, but I have deactivated the safe Z feature. In fact I have deactivated and adjusted all the things I can think of that might effect this. I know it is not a code issue because I can see it tell mach to retract 2mm.
What might be causeing this ?

Are you sure you're in mm mode (G21) and not inch mode (G20)?
It sounds like it is moving 2 *inches* instead of 2 mm.
Just a thought.

Yes it does sound like that Rick. The problem is I can see the actualy peck in the toolpath display and it is 2 mm the same, but you can see how it actually only goes two mm.
I might try and install a leter version of mach3 and see if that changes anything.

Benny do are you running in G98 or G99? The G98 will go to the Last Z pos Before the cycle was started.

For example:
G99
Z2.00
G81 X1.0 Y2.0 R.1 F30.0
X2.00
X4.00
G80
From Hole to hole in G99 Zpos will be .1

But in this example:
G98
Z2.00
G81 X1.0 Y2.0 R.1 F30.0
X2.00
X4.00
G80
From Hole to hole in G98 Zpos will be 2.0
I use G98 All the time because I can make the mill jump over clamps by changing one little line of code:)

I hope this helps Benny 8)

Did the G98/99 help your file?
