New bot assembly.

Well I'm not as far along as Henrik, but my day job is interfering with me. Heres a few pics of things. Had to make a cradle for VFD due to positioning, but all seems to be working out now. Man, what a PITA to post pictures & i'm using Pixresizer.What am I missing!

Neville,
I guess when you resize your pics to 640x480 they are still over 50k? Well go to www.xat.com (http://www.xat.com) and get "jpeg optimizer". It will reduce the kilobyte size of a pic leaving the deminsions the same. The quality suffers some but for web viewing its fine. I just took a pic into resizer, then into optimizer saved it and it only took 30 seconds. So you should not have a problem. I too have been frustrated with the restrictions, but as the grandkids say "too bad, so sad" lol.

I was wondering how things were going for you Neville. That looks great, yours is a 120-60 as well, I presume?

Everything proceeding according to plan?

[mikek]

Neville, your metal working to mount the VFD and control box looks great as do the tracks. I will try to come by on the way home from work today to see in detail. I will call first.

Jack, I did that & a test worked great - thanks very much, now I will have to take some better pics.
Henrik, Thanks, it will look almost like yours when I get the Marble floor installed :-) Yes its a 120-60, 8". I havent had much time to work on it so it may take a while. Other than omitting the feet when it was shipped( I have them now ) everything went very well with Mike Kelly & Wayne Locke's help.
Mike - delighted to have you looking over my shoulder as it were.

Thanks Jack

Welcome! My digital camera takes something like 3200x2300 and each pic is 1.2 megs in size so i have to change size and resolution. This seems to work for me pretty quick.

I'm in the final stages of assembling my PRS standard. All I can say is holy C---. This thing is as quiet as a church mouse compared to my PRT. Man does this thing run smooth. Before I installed the motors I could push the X-car down the rails with one finger, very smooth movement. I still have some issues to work out though. One wheel is riding high and the y car is binding slightly at each end of its travel

The Shopbot assembly manual says they can put one together in 6 hours. Before I'm done I'll have 30 plus hours of assembly time. I think ShopBot should consider revising the estimate. Any ideas how many hours you folks have in your assembly process?

I'm at the same stage 24+hours
I also have one wheel riding a bit high\
At the O-O end,how did you adjust it?
Can't wait to get it going!

[Towersonline]

Erminio, I have not attempted to fix the problem yet. I need to be in the right frame of mind to do it, lest I take out the big 8 lb alignment tool!!! It looks like most of the bolts on the gantry will require loosening. Probably 5 or 6 hours work. Right now I'm working on fixing a prox switch problem.

Hey guys,

Have you looked at the "Squaring the PRS Tools" document in the Support section of the web site...it has a section on where and how to make those adjustments.

I was able to fix the wheel issue/
After speaking to tech support,I loosen the 6 gantry
bolts and clamped down on the gantry -that didn't work completely-then I loosened the step motor-
clamped that up so the gears were tight to the rails-It worked!

[dray]

this is how squared mine up.. It took 2x but now its square within 1/64" or so in 4'.

It is critical for me to have it dead nuts because I cut alot of large pieces.

I'm still in the process of getting the PRS done. I spent most of Saturday and part of Sunday trying to get the controll box and computer on the same page. It would not jog over 8ips move was ok at 6ips. The prox switches would work ok some times then one or the other would quit--and it went on and on one problem after another. I finally dragged a 4 year old Compaq presario out of the basement VIOLA!! 20 minutes later it was purring like a kitten. Oh yea the computer that I replaced was a 3 year old DEll 5000.

Lesson -- don't hesitate to change out the computer if weird things are happening.

Bill,

Great to hear things are are going well. I'll second you on the smoothness and speed thing. When we first powered up the vacuum and went crazy (well, for me) with 6ips right through 19mm MDF, I nearly fell down. Whoa.

quote:Any ideas how many hours you folks have in your assembly process?
Our total tally so far comes down to ~72 manhours, but this does include many steps where one man is superfluous, and it also includes DC and vacuum system. The electrical bill is besides this however, so that's an added cost (two visits, he couldn't get it right the first time though I'm at fault for that as well, I was only charged for one).

We have been very cautious doing the assembly, cleaning and rigging things that ex post facto we could probably just have lifted up and bolted up, so this adds a lot of time as well.

Overall, we have spent about twice the amount of time it took to fine tune our Scheppach 3100mm stroke panel saw -- I'd consider 'bot install time as very handsome in general machine install terms.
