Right guys,
I'v got an issue with my machine, i cant work out what it is thats giving me this issue but im hoping you will know or know somthing i'v missed off my check list.
Ok i'v checked:
1. Measurements in my drawing
2. Toolpath settings in my drawing
3. Tool settings in my drawing
Ok so thats what i have checked pre Mach3.
In Mach3 i have checked:
1. Motor tuning (1280, 200, 50), drivers setup for 1/8th step
2. Zero All Axis's, REF All Home updated to new zeros
thats what i have checked pre machine (Rockcliff)
On the machine i have checked:
1. Rails + Bearings (levels, square's)
2. Drivescrews + Nuts (delrin drive nuts all nice and tite, leadscrews dont seem to have any issues.)
3. Checked Calibration (machine moves 20mm psyically when moved/jogged 20mm on the screen for mach3 (DRO?) )
My problem is:
The part is 3mm under size all round, the center hole should be 43mm but its coming out at 44mm (note this is only 1mm error), the bottom of the part (bit that fix's to the machine) should be 80mm across, its coming out at 77mm.
Any ideas guys? I thought maybe i'v not set the right end mill size in the design but thats set to a 3mm End mill and that is what i have in my spindle.
I'm telling the toolpath to cut on the "outside" of the vector, i really cant think of anything else i can check.
Please any info i can provide you with please ask and ill reply more or less instantly with an answer. The GCODE is posted below if you would like to look at that.
Cheers, Lee :confused: :( :( :confused:Last edited by Lee Roberts; 15-02-2009 at 09:14 PM.
