Jerry: Are there any more details about this file?

GC3: Good to know! I presume if you draw 18.25mm you get 18.25mm though...

New user - Last week my machine was very inaccurate after recently being assembled, thanks for the talkshopbot support. The problem was that the pinions were not tight and then when tightened they...

Reason I bought a ShopBot over anything else was also exclusively down to support and community, not just a machine. Thinking back to the last two months, not sure how I would have proceeded without...

PROGRESS!

I misunderstood what tighten pinions meant. This time I took the motors off and X1 and Y were both loose enough to fall off, the other two were fine. So did a quick cut at 9pm which I...

Do you mean from SB3? Here is that http://imgur.com/a/GOraZ

Tightened the set screws, they were quite lose as don't think that was in assembly manual and I unfortunately didn't check how tight/lose they were. Was excited as thought this was going to improve...

Your Test File = Not accurate. http://imgur.com/R5jqsPn

Measurement is 1.03inch x 3.09inch


Cutting speeds? Not sure if that means just all the details in the tool database, everything is at...

Did inches test, still out by similar distance. Did gap of 0.7inches and got 0.644 which is about 1.5mm out.

Also did a test by putting fillets in on VCarve, again no difference.

Both tests...

Just taught myself a new trick, didn't know that feature was there......I'm very new. :)

I use Rhino5, then VCarvePro that came with my ShopBot, then SB3 to play file.

Image attached that show various points of setting up VCarve. I export them to Shopbot file in MM....

This was intended to be 60mm long, but cut the hole 57mm (-3mm) and the leg 63mm (+3mm). So I remade a top that had the holes as 66mm and got holes as 63mm (-3mm) which...

Both are messed up, but differently.


I need to get something built, so figuring out if it needs to be +3 or -3 in different places and is...

After more tests, its seems that the cut is consistently out by 2.85mm on a range of cuts 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm and 36mm.

I have figured out that if I convert lines...

pp?

Indeed well greased. This is a brand new machine, so I followed instructions and well greased it.

Yes, I did the distance test. Tested 2000mm and it is perfect.

I also made a drill hole and measured the internal diameter of the drill hole as 6.33mm, so pretty accurately a quarter inch that...

Was recommended there to copy and paste Gcode/Shopbot file of a 10x10 square with bottom corner at 0,0,0.

Posted on Reddit too. Someone noticed the dimensions cut are all between 87%-89% of the specified dimension. Not sure what this means, but likely something there....

Wow. lots of great responses! Thanks for the support.

Jerry/Khaos: I'm not sure how bit sizes are meant to be. It is certainly 0.25 inch at top of bit on the smooth part, but the flute part is at...
