First cut problems
« on: June 16, 2008, 08:35:27 PM »
I loaded the roadrunner program,set up my material.I measured the tool diameter and put it in however it would not save the tool measurement.How important is these two measurements?Then i tried to set spindle speed but again it wouldn't let me save that number.How important is this number?Anyways i finished seeting up and started cutting.Everything went great until around line#1160.Mach was still running but my mill stopped.I had to reset the servo motors,back up the program to line#1150.Everything reversed fine but somehow the depth or the z movement was to high.How do you reset the z height during the program so you don't have to start over? Where did i mess up?????

R U runing a licensed version?  There is a limit on the lines you can run w/o a license and maybe you hit it?

Not sure what you mean by "Save" spindle speed and tool diameter.  Spindle speed is usually a command written into the G-Code of the program you are runing (i.e. S1500)  and tool diameter is usually called with a M6 tool change command using the the tool table.  Or perhaps I am misunderstanding something and you ar referring to compensation?

Hi, D CUSTOMS

The start of Roadrunner file: Starts at lower left x0 y0, Size is x 7.7282 y 6.3797 (You can see these values on Tool-Path & Diag. Screens top right.

This G-code file doesn't require a tool setup, Best I can See.

Best cutter to use is a V engraving cutter, Jog to a  x, y, position that allows enough +x,+y room on your table and Zero X, Y axises.

Jog Z to about 0.060 above top of material, Zero Z axis, this will give you a .040 cut depth.

Rapids will be z +0.200 and cut depth z -0.100 (-0.040 cut in material with cutter zeroed at 0.060 above material).

As "Sid" stated without lic. 500 lines of G-code will be executed, But it went to line 1160, Not sure what caused that to happen.

F60.000000 ; sets feed-rate to 60.0 inch per min for G01,02,03's and G00's at your velocity setting unless the FRO % is in over-ride.
G0 X0.000000 Y0.000000 Z0.200000 ; First move Z up to + 0.200
M3 ; Spindle ON

S60.000000 ; Spindle speed 60.0, If you have spindle speed feedback you will want to edit this to a faster speed.

G43H5 ; Apply tool lenth offset + to H5, Don't think you have tools set up, should have no effect
G0 X0.000000 Y0.000000 Z0.200000 ; Redundant line
G0 X1.179950 Y4.004260 Z0.200000 ; position to start for cut
G1 X1.179950 Y4.004260 Z-0.100000 ; Z down to -0.1000
G1 X1.179950 Y4.004260 Z-0.100000 ; Cut continues

Hope this Helps, Chip

I do have a licensed version.What i meant about saveing spindle speed is that i put in the speed in the lower right corner of the mach screen and tried to enter it in but it would defalt to 0.0000.I set the spindle speed on my mill to 670rpm.I overrode the feed rate down to 6.00 because we were breaking bits.Is this normal to bring the feed rate down this low?How do you know what tool diameter to use?Before the motors stalled they sounded like all of them wanted to engage.My speeds and accelerations are low i don't understand the problem.Chip i will call you later if i dont hear from you.

Thanks, Chip
