Could you let me know what oring material you used and what the channel cut depth was?

I developed something similar and tried closed cell backer rod 1/4" and 1/4" rubber oring. Issue I had on...

I saw all those as well when I was building my machine. I worried and fretted a long time over taking the chance and rolling the dice on what I would get. Many got a perfectly good spindle but...

I made mine at 40". It is a 50x50 machine and I am 6'. I have wished many times it was about 4-6" lower. Easier to load material, reach center, sit at it while working, etc. etc. I would...

Not sure if it helps and I am a newb but here is a vid from vectric on tiling in vcarve.

Thx Gerry

I will give that a try. It was cut raster with a ramp in but was conventional. I will try the offset and trial conventional and climb. I really appreciate all of everyones help in...

Andrew.. Yeah I am about to come to that conclusion as well. I am about to put Poplar on my hate list :)

Ben.. The back walls were vertical and not humped. I think it is an artifact of the...

Gerry:

Here is a quick pic I took headed out the door to work.. Hope it shows what you were looking for. The helix direction between the upcut and downcut look to be opposite to me which is...

Went up to 300IPM today with basically the same results.

sigh....

Well I did some test cutting on a pc of 12 x 7 x 3/4 inch poplar. Below is a picture of how it was supposed to look. The numbers under each block are the IPM it was cut at and the legend...

Thx for the reply. Hearing someone experienced say it is not outside realm of believability helps my confidence. I am going to be doing some test cuts this weekend and hopefully not add more...

I have a machine up and running 3HP water cooled spindle

I am trying to get a handle on feed/speeds and avoid learning via broken bits and empty wallet. Rather than ask an open ended...

Thanks for the quick answer Al.
I really appreciate your expertise on the forums. I have read many of your posts and learned alot.

I have searched and scoured but found no clear answer or maybe just confused myself more.

I am coming from the garage sub-panel 30 amp breaker with single phase L1 (110V), L2 (110V),...

I would probably redo the trucks. Use something like Standard Linear Motion | CNCRouterParts or their vconsystem to retrofit. I have no wiggle in mine since it is fully supported.

Interesting concept. Something to consider for sure just for simplicity sake.

I am about ready to install the water cooled spindle on my machine. I have seen both gantry mounted with a small reservoir and mounted under table with tubing run through cable carriers to...

Thanks for the alternative suggestions to cut3d. I will go research them. In the build of this CNC machine I have done enough research to earn a Phd I think. When your buddies start talking...

All:

Thanks for the views. I was hoping to get a read from someone that had done similarly to make sure I was not overlooking any capability. I will ask on the vectric forums as soon as a...

I have been looking and trial running some of vectrics software. Love the capability and it is well aligned with my goals fo signs, sculpting, and rotary turnings (wrapped 4th axis work). ...

Thanks for the tip. Worked nicely...

WoW! Amazing pics and very thought provoking.

At the risk of sounding stupid could you cut the raceways for the smaller sized balls with a straight bit or normal ball end then cut a duplicate top...

Love the build notes. I am about to embark on this journet and the PMDX items are on my list as well as a water cooled spindle.

One quick question... Why did you decide to run 4 PSU? ...

Thank guys. I knew it was a "many factors contribute to this" type question. Good advice on I can choose where to spend the time (on the machine or in my hands sanding. I suppose I was jumping...

LOL.. I guess I inadvertently asked for trade secret tye stuff?

I have been lurking and scouring the posts in preparation for my first CNC router build. One question though is if your making signs/3d scuplts, routed picture frames etc. how much finish...

One more note on the piercing operation.
I have seen some folks get sround this by adding a 4th axis to the system and rolling the torch up to vertical then proceeding. This greatly aids the...

To add to alex's post. The reason that automated machines need to go bigger is due to the difficulty of piercing thick material. If you decide to go with the 81 you can have leadin cuts and do...

How much and in what sizes???

Steven

Bailing wire.. They weren't even sophisticated enough to throw in some duct tape.

I hope OSHA doesn't visit soon (chair)
