so we are all good? !!!!

After being very frustrated about the squareness of my new SS router I was ready to just live with it being 1/8 off from side to side.
What you have to remember is that We the owners assemble the gantry part so it changes from the factory.
Here is what Ben had me do.
1 Put in a 60 degree v bit or sharpest piont bit you have.
2 on the spoil board make a xy zero anywhere near home positions.
3 (in manual mode) dip the v bit in to make a small mark (spindle running)
4 lift up and go x 40" make a mark with the bit
5 run out Y to 60"
6 Measure to see that they are 40 40 and 60 60 them measure diagnally.
(I put a screw in the two farthest pionts for easier self measuring)
if these numbers are diferent it is not square.
I got 72 1/4 from home diagnal and 72 1/8 from tool side diagnal (1/8" difference)
I started with razor blades as spacers in the draw bar mounts. it got closer but I ended up going to the auto parts store and got a Feeler Guage I took the razor blades out and put in .03 Feeler guage thickness re tightened and losened the pully mount on the ball screw plate and ran it back and forth then retightened it all.
to the best of my ability to measure I am now within .003 or so it is so close I don't care about it and that .003 was when I did a 15" point to point box square so the eye could never see it but you can see how to fix this now and it you where board you could sit and go up or down with Feeler guages as spacer .001 at a time and get EXACT.
The draw bar ball screw cnc's are diferent than rack and pinion systems to tune but I am very happy with the squareness about it now and yes SS was very helpful to get this fixed I have just lived with it for the past 4 months because for signs I did not realy need it that square you could never tell on sign letters.
so we are all good? !!!!

yep it is so close now that the .003 diference diagnal measurements on a 15 inch box does not concern me when it was 1/8 inch it did. I could put in a .004 or .005 schim and I may some time but the parts on the table move more than that .003 so it is very accurate for me now.
excellent!!!

Glad to hear you have it figured out.
Question for you on the ShopSabre...they say they weld the table and don't use bolts. Does this mean when they sell a machine that they crate and ship it fully assembled?
I'm asking because I'm wondering if I will be able to fit the machine into my basement. I can get long pieces in through the window...and larger pieces through the standard doorway (hopefully
The largest component is the table which is 63"W x 111"L. It may work.Originally Posted by MJIndustry

the garntry is separate and the legs are separate with cross bars angle iron. the table bed itself is one peice and it is all very heavy I would not suggest how to get it through a window.
Wow! Thanks for the reply, looks like a great machine but the chances of that going into my basement are very slim.
Looks like I might be back to the Shopbot PRS standard 48x96. (I think it comes in a lot smaller pieces!)
I am not here to judge anyone but I would not ever put a cnc in a house.
from my experience.
#1 very dusty especially in certain woods.
# 2 Noisy
# could cause many health issues it that dust is all over your house all the time.
is your heater or airconditioner inlet in the basement any I have seen are. it will pull all that all over the place.
Flamable and dangerous setting for a residence.
if you are having a hard time getting the machine down there how will the wife love you trying to get full sheets of particle wood and such down there.
I don't know what you are planning to do with it but there are better small machines out there if this is a hobbie or I wouyld add on to your garage or get another out building in you yard.
you can do what you want but I have seen the hellasous mess that a v bit in particle board can make so you can't see across the room even with a dust vacume it will get very dusty down there and you have to get that all in cut and haul it back up.
Just My Opinion
later
i watch many forums and shopbots daily and while i would not recomend my machine (it is a welded monolith) i would ask you what you intend to do with it in a basement as a primary function there are reasons to understand wanting to have a cnc anywhere and if i were to process panel daily a 4x8 is a requirement, if i were to process 4x8 once a month i'd just find a way to do it another way, if you are going to hobby,carve make signs then a 4x4 shopsabre or buddy 32 or 48 by shopbot may be in better order. kustom is right dust removal by it self is only going to pass through your kitchen so many times before the wiffe say's @%^*## this.
so what do you want to do with it?

Its the wife that wants the machine, I have warned her of the dust issues yet she persists.
We would put it in the garage but we are in Northern Minnesota and it's very cold in the winter and I know from experience tools break in sub zero temperatures. We have a garage with enough room...
I'm from Fargo. yeah its cold up here but insulation and a heater in the garage would save you hundreds of headaches. with getting the machine set up and getting materials onto the table. not to mention the room you need to manuver materials around once you got them downstairs.
It's great that the wife wants it but you guys have no idea what these machines make for a mess I was shocked the first times I fired it up. it makes increadable High pitches screams at time with certain materials and bits. the spindel is quiet as heck but it is the bits cutting you hear. over 100 DB easy at times... it made way more of a mess than you would ever think it could. I will look for some pictures of what a mess it makes.
try to make the garage work.
when I went to SS in the cities they did a small 3x3" 3D carve and I was like yeah it is quiet and clean. yeah it is for that but try to cut something it throws a rooster of dust 3' out the back of the bit.
