New Build - 1000mm X-Carve - Questions

Spent most of the day re-arranging stuff to fit the bench for the X-Carve. Had crazy plans for an awesome cabinet with drawers and other stuff. All axed to get this assembled and running asap. Found a 4ftx7ft commercial door slab almost 2" thick on craigslist for cheap. Cut that down to 54x48 for the work bench. The X-Carve front will be towards the right so longer stock can be used.

Gusseted pocketed Kreg HD screw legs, with a bottom shelf. It’s pretty rock solid and doesn’t move or flex at all.

Squared frame/wasteboard with help from Phil’s page.

Have a question and need help.

In regards to the 9mm wider upgrade parts from Open Builds, I found a decent picture here from Phil’s post…

In the first picture, it seems to me that the factory aluminum spacer is used with a washer.
But if attempting that the nut barely threads the screw.

What is the correct order for the open builds pulley? On paper in the attached picture do I have it right?

One search and video on openbuilds shows an inside/out but pretty sure that is not applicable here as the bearings are identical on both sides, couldn’t find any decent step by step pictures or step by step instructions for assembling these idler pulleys from Open Builds.

The OEM pulley bearing metal sticks out a little bit on one side, the Open Builds pulley does not on either side.

Have to use the OEM screw as the open builds screw is too short.

Do I omit the oem washer? It seems to work that way, but I think I see the washer there in Phil’s first picture in that post above?

Thanks!

So I do have the correct order(technically, the plastic idler should be swapped left one with a bearing)? I’ll run to the Lowe’s or home depot tomorrow and see what I can find then.
Just want to make sure I’ve got the order correct. I can’t tell in your picture now if the washer is there or if it’s just a reflection…

I just installed the same pulleys. I’ll take a pic of mine shortly for you!

Awesome, thanks!

I used only the wheel, bearings and the nylon spacer(between the bearings) from the openbuilds packs. I didn’t shim them beyond the original aluminium spacer because the shafts on my motors aren’t the longest. Although I may shim them by 1 washer if the alignment doesn’t work out. You can see what I’m talking about here in my build log. I am using Phills belt clips and there’s a slight plane difference near the front of the gantry(I don’t think it’s an issue but if I knew about it while I was putting it together I’d have just thrown the extra washer on it.

So Screw->carriage->aluminum spacer->(optional additional washer)->idler assembly->washer->nylon nut works with a 35mm screw. A 30mm cuts it close. I only used these 40mm because I didn’t have any other 35mm(hence the nylon spacer you see).

The potential additional washer would go on the side of the aluminum spacer.


The additional spacer would prevent this slight angle but for me it’s only this way due to short motor shaft. Since you have the 269oz, you have plenty of shaft to move you gear out and in turn shimming your pulleys the additional 1mm

Thank you so much for the detailed pictures!

Of course! Hope it helps. Trying to detail any issue I run into in my build log. The table looks pretty awesome btw!

Installing CNC4Newbies Z to the Z bracket assembly now, think I’ve got it right, seems straight forward…

Couple underside table pics. 14-2 1/2 HD Kreg screws pocketed, construction adhesive at each point, it can’t move/flex/rack in any direction.

Ok, so can I flip the bracket that holds the dewalt upside down to get another inch or so of height? It appears it would work or is that a bad idea?

And the CNC4newbies z, the set screws on the coupler go right into the drive screw itself? Seems the only way but wanted to make sure…

And the bracket that holds the dewalt, it is super snug even with a screw driver trying to press it apart the router does not want to fit…

Off to lunch now, back in an hour…

Using the CNC4newbies Z Axis, does that mean I can flip it then?

No worries at all, guess we’ll keep it in the correct readable label orientation to be safe…

You probably could flip it but I don’t think you’d gain anything and may cause other issues. The router may not extend past the mount and you need it to extend under the mount.

You can try it and see before mounting it. The key thing is that the Dewalt hangs under the bottom of the mount.

Stopping for the day.


It seems like there would be a benefit to flipping it, has anyone?

It’s attached correctly, but might flip it, maybe flip after full assembly to see if it gains anything? Not sure…

If you are talking about the black stock bracket then you could. I think you would gain maybe an inch. Just check the orientation of your router so it doesn’t hit the nema spacer block. Only 4 bolts to give it a try!

Yes, I was able to crank down on mine fairly good… just don’t forget the loctite!

Status update no real new pictures, but soon.

Have the side belts installed along with Phil’s belt clips.
So side motors/plates installed, side belts installed. Top belt will be done likely Wednesday when we resume work.

The gates belts are…wonky, tilted, assume with time they will straighten out as they acclimate or are used?

Used the video here as a reference ManhattanWoodProject Video below (and PhilJohnson who continues to be super helpful even with my beginner questions). Having never tensioned a belt in this manner…

I was initially lost on how you do that when thinking about it as I thought to myself well if I pull up I can go to 50 pounds… aha at 1" height as a reference point, now it all makes sense. I’m learning stuff!

We are moving things super slowly as I read and remembered that it’s important for proper care of the motors.

PhillipDanner - we are going to assemble everything and when it’s all done and running, then flip the stock bracket and see what happens.

Thanks again everyone for the help/insight/recommendations etc! If I say thank you too much, blame my parents for teaching me that a person should be thankful when people lend their time and knowledge to help another person - especially freely as it is here! And if I didn’t specifically thank someone who ever should be because I am always running 1000 miles a minute it’s merely an oversight.

Thanks for the pictures, we left the washer on as it seemed to and does line up everything correctly.

Next question…

In regards to the upgraded 269oz motors…

Blue from upgraded motor goes to factory white wire? And the others match up red/red/ green/green black/black?

Makes sense to me, but want to be sure, couldn’t find anything searching.

Yea that works.

Soldered and done(with that step). Thanks!

Machine is up and running(dust collection next).
Did end up mounting Dewalt spindle mount upside down. - Great idea for those with the CNC4newbies Z.
Sideboard initial idea was to mount it vertically but nearby, didn’t work out.
Drilled hole into table for wiring to drop down to go to X-Controller which is mounted to piece of plywood attached to table trusses/legs.

Attached X-Carve to table with countersunk screws direct to tabletop(4 of them).

Calibrated steps with this video from Manhattan Wood Project

And Phil’s calculator

http://www.designsbyphil.com/x-carve-tips.html

X steps ended up being 26.616 and Y steps ended up being 26.646 with the upgraded 269oz motors, 9mm belt/pulleys.

Z steps are fine at 50, calculated results should be 50.063, but measuring after altering to 50.063 ends up being 1/16th off over 5 inches instead of 1/64th off with 50 even. So 50 even it is.

Will be updating to 1800 max z rate and 300 z accel rate sometime later today hopefully.

AHEM…

So…

When I read with the CNC4Newbies Z upgrade more than a few times it’s important to tell the gerbil on the wheel to run slower(or rather 1/4 baby steps) else you’ll plunge the bit too far…I noted that, and noted it again, and remembered I should really do that first thing.

Everything seems good, swapped wires to sort out X/Y being backwards… Move forward, goes forward, move back, goes back, move left, goes left, move right, goes right. Up/up, down/down. YAY, let’s carve something!!!

Ok, initial easel carve…

Had a customer in the office so told my friend sure, good to go, of course I’m sure, remembered everything it’s all good, be back in a sec…

Friend started the carve…and POOF plunged too deep into 3/4"plywood and then wanted to move sideways…

Then I realized I had to remember to do something…something before the first carve…hmmm.

Someone(me) forgot the important step(ha, get it?) of $102=50 with the CNC4Newbies Z.

Goodbye bit. Hello deep hole. Stop button is a neat thing!

What’s left to do?

Cleanup wiring under table now that we know everything seems to work.
Setup soft limits per Phil’s very useful pages.
Figure out dust collection mod to mount that to CNC4Newbies Z slide 6".
Install and configure Triquetra software.
Install V-Carve, halftoner, GRBL, and a few other programs(Pixel CNC demo for sure).
Figure out dust collection/sound proof lid/box (this will lift straight up).

Start working on awesome projects and posting them and asking a bazillion other questions as I do so.

Thanks again to Zach Kaplan(who I am happy to see is active on the forums again) and John Hayes at Inventables. To PhilJohnson for all of his help, answering my many questions and those great belt clips for the 9mm belt ugprade. To everyone else as well in this post who has answered questions, provided suggestions and to those in other posts indirectly where searching the forums resulted in an answer.

Have a neat idea for a group project I will post as soon as my machine is fully operational.
I have to do some prototyping and more thinking before I post that.
