how do i set "top of part"?įirst, I highly recommend that you change your workflow at the CAD stage to MM instead of CM. I remember seeing the the lace angle, i'll try the switch!Īhhhh "top of Part" yes I would get an error when trying to calculate tool path that said something like "part is X value is above top of part". It can be in cm mode, i import in inches and change the part preference to inches and works without incident. still doesn't seem to like it when I open a cm Drawling in it. I have the bobCAD so it is always set up in cm. You have to set the "top of part" in the feature you are using though, to be above the top of the 3d model.I'll look into the "merge" Option. Your part can be anywhere you want it to be, like, above z zero. I dont think V24 did much work with the stock yet. If your in the 3d toolpath "slice planar", there is a "lace angle" value set on the patterns tab. If you want BobCad to always be in cm, set that under the preferences default. In BobCad, set your units to cm under the part peferences, then "Merge" the drawing into those dims. any help you would be willing to provide would be greatly appreciated. I'm sure this is supper simple and I'm just missing a big part.

Wouldn't it be more efficient to move the full length (160cm) in the Y and step over X and repeat? BobCAD cuts along the y direction then moves up X axis a small amount then across the y in a zig zag pattern (repeats). Also the stock will not necessarily be a uniform thickness 15mm-13mm.ģ.) is there a way to change the direction of the slicing in 3D mill. So, zero the bit out on the table top then cut, correct? so why does the part have to be in the -Z axis. My stock is 1.5cm (Z) 15cm (Y) 183cm (X) and I would like to have the CNC cut down to the.

Which I have figured out how to do but i can't figure out how to accurately cut the stock to thickness. When I import it into CAD and compute the tool path it wants me to to put the part in the -Z axis. 160cm long (x axis) x 14cm wide (Yaxis) 0.2cm in the tip goes up to 1.2cm in the middle (55% of length) and then back down to 0.2cm in the Z axis. The shape I'm looking to cut out is a double sided wedge. Have I missed something obvious?Ģ.) Once I figured that out, 2D cutting has been no issue at all, however I would like some explanation on 3D. My fix had been to size the drawling from CM to INCH in autoCAD before importing it in. I've tried every different scale it offers (mm-meters, inces ect) and nothing seems to work. Just some quick questions:ġ.) For the life of me I can not import a metric (cm) drawling into BobCAD. My CNC runs off of Mach3 and BobCAD (V24) so I've had to relearn a lot of stuff. First, I'm new to CAD (Biochemist by trade) so i have been heavily self taught and I learned to do it on AutoCAD.
