Hi there! Using Mach 3 on a Seig KX1 and have encountered a peculiar problem. Using the circular pocket wizard I'm trying to use a 4mm dia cutter to make a pocket that's 5.2mm dia. When I run the program the pocket is oval, not circular and I get the error message: Maximum < Minimum. Can someone explain what's going on? ???
-
One of your settings of MAX is LESS than the MIN value. That would be an error as Max HAS to be larger than Min.

Can you be more specific on which wizard you are using. I do not think the Newfangled wizards can do anything to generate that error message. Does the error come while running the wizard or while running the gcode it generates?
-
I'm using the 'circular pocket' wizard. I haven't found a tutorial on how to fill out the wizard correctly but I've used the 'cut arc' wizard before to radius the ends of parts and this one doesn't seem to be much different. Still and all I've obviously done something wrong. I was wondering if the cutter is too big to cut a hole just a wee bit bigger than its diameter; could that be the issue? Or possibly the percent value of step-over is too high? Or possibly something else. Confused I am! ::)

What are the settings that you used ??

OK here we go; natch the settings I originally used in the wizard are in the laptop that died last night so I'm doing this from memory:
Wizard screen values:
X Center Pos: -13.5
Y Center Pos: -3.5
Tool Dia: 4.0
Pocket Dia: 5.2
% Step Over: 70
Ramp Dis: +2.0
Feed Rate: 70
Feed Plunge: +80.0
Depth: -4.0
Step Depth: 4.0
Rapid Height +0.1
Spindle RPM: 4000
CW
mm
--Now here's the G-code I've copied from the program:
G00 X-13.5 Y-3.5
G0 G49 G40 G17 G80 G50 G90
M6 T0 (Tool dia 4.0)
G64
G00 G43 H0 Z0.1
X-13.5 Y-3.5
G01 Z-4 F70
Y-3.5 X-12.89 R0.305
Y-3.5 X-14.11 R0.61
X-12.89 Y-3.5 R0.61
Y-3.805 X-13.195 R0.305
G00 Z01

Your stepover is much to large for the size of the pocket you are cutting. Try 10%

Will do. Be back with results in a bit..
-
I dont see any circular moves in that code- those lines with R values follow a modal G01 so ought to give an error. It needs a G02 or G03 in there.
-
HIYA Ron that is because the Stepover being too large and there is no error checking in the wizard. If you reduce the stepover to 10% it works. That one is a VERY EARLY wizard by Brian.

--Well gang I tried it at 10% and got the same error message. So I changed it to 5% and got something that looks right, but it's a gawdawful loooong program. Have yet to run it because I'm trying to get it plugged into a larger program in the right way. Ultimately I'll have 6 different circ-terps in this particular part. Waiting for Mow, blow and go; once that's over I'll take a whack at running it! :D

It should not be a long program with your settings. The small stepover is needed because the size of your cutter is almost the size of the pocket you require.
