Thank you. Yes after cutting v-slots I need to face it to make it perfectly square. I don't have a cnc mill. That's why keeping v-slot's as it is, makes the job a lot easier. Makes the machine more precise.

 

Hey Ronald,

Was wondering what's your recommended maximum size for the routy 290? Would 18" x 24" x 6" be too much? I just got my v-rails in today and I'm still contemplating how big I want this to be before I start cutting.... Thanks! Looking forward to your reply. Btw.. I didn't get enough v-rail to add support beams across the bottom.

 

Hey Ronald,

Thanks for getting back. I basically want the ability to 3d print with the routy as well. I did get the extra acme rod plate and bearing and lock collar as you mentioned before. I'll take a look at the Ox and see what you mean about doubling up. Sounds like maybe adding an extra v-slot for extra support?

 

I gotcha... basically adding another v-slot and v-wheels for extra rigidity.... thanks again for your suggestions.. guess i'll build it how i originally speced it out for now and go from there.....

 

Hey there Ensari,

I see you're setting up a routy 290 as well. What is your build volume looking like? Have any idea what your z axis travel will be?

 

Z axis travel is easily adjustable. Right now I have 4-5 inches. I don't know about the rigidity for now. Still building. I work for a CNC company, asked to use their machines to face(mill) the ends of the v-slots. V slots that we get, are not perfectly same size that makes the table out of square. I would suggest you the same. For X and Y i didn't shorten the v slots. Made same changes from the original design. This gave more travel on X and Y. Z needs more support. I will share pictures soon. I m using some precision tools to make the router as square as possible. Will be good to share the experiences while building

 

Thanks for your reply! Looking forward to seeing more on your build.

 

Hey Ronald,

One more question and I'll quit bugging you.. These are my proposed dimensions for my routy 290 build. Do you see any problems with the following cuts? I basically just worked off your measurements and added/subtracted the proper lengths:

460mm x 610mm x 150mm (workable area) 18"x24"x6"

Actual v-slot cut

X - 603mm
Y - 790mm
Z - 312mm (lead screw - 300mm)

Table Support cut

591mm

X axis support

602mm

Y axis sides

312mm

Legs

140mm?? Will the extra 20mm make them flush with with Y axis rails?

 

I have a miter saw but for wood? Would it cut? Or yours for metal?

 

You have a nice miter saw with adjustable speed. Mine is single speed and 3500rpm. I think it's too much for aluminum. I will buy one like yours. Thanks

 

Hey everyone.. I made a bone head move.. I'm assembling the x-treme solid v-wheels and didn't realize one of the washers had to go inside of one of the bearings in the wheel. I just snapped the bearings in both sides and thought all was well. Don't really see an easy way to remove the bearings and insert the washer. Should I be ok? I did this to four of them on the z axis gantry plate. Thanks!

 

thanks! yeah... after an hour i finally got the one side off.... dang that was tough.. lol thank god i didn't do all 16 like that!!!

 

Just wanted to share my progress with my build. So far so good. Build envelope is 18"x24"x6".

 

dang it.. just noticed I mounted the L brackets the wrong way on the x axis.. oh well... i'll fix it tomorrow.

 

Your z axis looks very long. I think you may have rigidity problems. but its easy to fix, if you dont like it

 

Yeah im going to do some testing and see how it performs at its current height. I hope it works as i want to 3d print with it too.

 

Good call! Didn't even take that into account. Guess I'll have to come up with an easy way to mount and dis mount this thing.. Although it's not really bad as it is......

 

Hi,

Arduino Uno, even a clone can be used, needs to be flashed with GRBL

• Set for X and y axis speed to 5000mm/min and 50 on aceleration, steps per mm at 57.14 (make sure your shield is set at 1/8 step)
• Set for Z axis speed to 2000mm/min and 50 on aceleration, steps per mm at 200 (make sure your shield is set at 1/8 step)

I adjusted the steps per mm 57.14 for x and y, 200 for z. But I couldnt find x y z axis speed. And acceleration is common for all axes. I m using universal g code sender. How can I do that?
Thanks

 

Thank You for all your help Ronald.
I finally finished. Now I will start developing that. I have almost 390mm(14.8"), Y travel and 350mm(13") X travel and 4" Z cutting height.
