48 x 86 upgraded PRT Alpha with gear reduction motors and gantry with 12" Z travel and 5hp Colombo spindle. Love, love, love this machine but I'm moving overseas. Purchased new in 2005. Colombo...
12" travel Z axis. Originally mounted to a Shopbot PRT Alpha but could likely be fit to a home-built cnc as well. Modified brackets for added rigidity and an adjustable height mounting plate for...
Problem solved, thanks to all that offered suggestions. Turns out it was a harmonics issue with the PC and control box having the same power source. In the end it was our electrician that figured it...
Yup, that'll be next. There is a shielded cable on there now but things do wear out. This machine has been very reliable and at times has run for ten hours a day, five days a week.
When I closed my...
Thanks Brady. Forgot to mention this is a Colombo spindle without speed control through the control box. Will go re-check all connections and voltage next.
Have been running this older, upgraded Shopbot PRT Alpha and Colombo 5HP spindle for years with few issues. I've been controlling it with a Sony Vaio which has been absolutely bulletproof...until...
Thanks Dave, I'll do that.
Yup, just as I suspected...The Kent dust shoe doesn't play well with my older style gantry and a Colombo.
Thanks Don, I've sent them an email inquiring about fitment.... given the gantry geometry on these machines I'm thinking an extra long plenum may be required. My machine is an older PRT Alpha.
I'm wondering if there's a good dust boot available to fit a 5HP Colombo spindle?
I've been using a self-built unit for years that was marginally effective but I finally broke it and need to...
Thanks fellas' I appreciate the feedback!
Having retired last year I'm just about ready to re-assemble my Shopbot in my new home workshop which is nearing completion. Noise will be a big concern and I'm wondering if there's any real downside...
[QUOTE=Gary Campbell;195739]Inside the spindle there is a contact bushing from the case to the armature. You wore yours out. Time to invest in a clip.
Thank-you Obi-Wan!
Years of flawless performance and this issue just popped up...Older PRT Alpha equipped with a 5HP Colombo spindle. When setting the zero with the plate the cutter is not grounding, as in no ground...
Yes and I dare say I could've done a better job of it. I worked for several years for a company that specialized in high end carved, sandblasted and engraved signage and I learned a few tricks for...
Yes, it's a far sight faster than sculpting and a great way to go in rush situations as these were.
With the combination of cnc and laser we were able to get this rush job out the door in just under three hours from the time we were emailed the drawing. It would have been quicker but it was the...
The designer on a new, locally shot series was kind enough to send me some "after" pics of a couple of cnc cut plaques I did last week. Stagecraft doesn't provide finish painting as it would be an...
Ha ha! Unfortunately I can't share files for that gate or the Atlantis gate. We sign ND agreements and I still work in the industry. Believe me, nobody was more disappointed in Universe being...
WOW! I just happened to stumble across this post while reseaching fabrication of live-edge clocks. As it so happens, I was the head graphic designer/fabricator on Stargate SG-1, Atlantis and Universe...
Thanks Joe, figured it out. There were a couple of allen bolts hiding behind a plastic insulator. Once those were removed (after making sure power was off) it became clear how to take it all apart.
My fan has died and I've ordered a direct replacement online. The thing is, I can't see how to disconnect the old one. I've removed the fan housing from the top of the spindle and I can lift (just)...
12 inch PRT Alpha Z Gantry with added removable adjustable height mounting plate (currently configured to fit Colombo 5HP spindle).
In very good condition. Offers?
David, I would recommend you join the forums at www.signs101.com and explain your position and ask the same question over there. The forum is full of folks that have started their own sign shops, me...
Business is a bit slow at the moment which allows me to play with the equipment on personal projects. I just finished a sign/fence panel for our VRBO suite. First time working with sycamore, really...
