how did you learn how to use sprutcam?

@leloodallasmultipass Watched youtube videos and signed up for Dukes4monny's paid video training - it was cheap and very helpful. Tormach also has more youtube videos available now.

I love this machine my only concern is its feedrate speed. Can this machine go faster in G00 or your stuck with a max speed of 90ipm? Please let me know, thanks. Loves your vids BTW

@Trajiq187 Spend some time on tormach.com - they have a plethora of information, spec sheets and white papers available which cover details like tis. Yes, max is 90ipm. If you're concerned about that 'limitation' versus a VMC rapids of 450+, then read their white paper on the PCNC design - rapid movement doesn't save that much time in a standard machining operation.

Great Vid!!

@DalesTec Thanks!

@saunixcomp Hey thanks for the reply. Yeah i know it doesnt safe a lot of time because you have to respect rpms and feedrates when cutting anyways, but i would like it to go faster between operations. I was wondering if its possible to upgrade it like swaping the step motors or something. I'm currently working on a Mazak at school and im just used to it i guess lol. I do not expect a mazak out of a tormach either but was just wondering. Cheers

@odonatas2 Noted re: screw instead of jobber. I've always been a fan of spot drilling & find that using a 1/8" pilot (which are cheap) helps save the tip and provides for better feeds & speeds with larger diameter drill. An even better option is using a 3/16" or 1/4" carbide spotting drill which can spot, pilot, chamfer, etc - and is plenty stiff.

You can post a link to enco if you remove the "htp://ww" part [spelled incorrectly so youtube would let me post]

[odonatas2]

May I suggest when the thickness of the material warrants you consider using screw length drill bits such as on page 26 of the Enco catalog rather than the jobber length you are currently using? They are so much stiffer that you'll get accurate location without the spotting operation, and most of the time you'll also get accurate diameter and not have to use intermediate drills.

P.S. It seems YouTube won't let me post the link to the Enco page.

@magnum164 Yes, I have hand deburring tools. When I said I couldn't deburr the contour of the part, it's because the CAD had a different contour profile than the CAM output because I didn't program the end mill radius' in the CAD...
