Sure you can show more! Great work, it looks like you are enjoying it !

Edit: I had to watch it like this:

 

By the way, those triple-hole brackets should be behind the gantry, or you can leave it like it is now and have 20mm longer cutting area but less stable gantry.

-Ronald

 

Now less force is needed to create a parallelogram out of the gantry, looking from the top onto it and seeing the back brace and X axis V-Slot as the parallel part... If that made sense...

For example, if the back brace would be further away from the gantry, the whole gantry would be more stable as well.

 

Hello @speed,

Yes you need to unless you use a 250mm 20x40 V-Slot.

I'm working on a new "Routy" that should be at the same price level as the Routy 290, let me show you a render:


It's still not released and there will not be a manual to build it, but I might make a build video (1 day work vs. a month for a manual).

-Ronald

 

It's 290x290x118mm when you use 500mm stock V-Slot. Parts without the wood, PSU and CNC controller board is just under 450USD; Z axis motor included, NEMA23, other motors are NEMA17 with 14t pulleys.

-Ronald

 

Just looking at what the market wants, so, larger cutting area... And for 471.90USD (Black V-Slot included, this added 4USD to the cost ) it won't break the bank, again. Cutting area: 810x290x100mm.


On Monday I get some samples of drag chains; one of 1.2m can be mounted to the back of the machine for cable management and on the sides a cable of 350mm will power the X axis motors (no drag chain needed there). From here we go a step up to 720x720x100mm and last 1220x1200x100mm (C-Beam all over, double plates and table/bench design included (plywood/V-Slot/C-Beam) .

Anyway, the previous Routy was about the price of this machine, sure the wood will add some to the price but still, anything under 500USD we consider a good starter project. Remember that all these builds can be easily upgraded/expanded over time, when needed, without paying for a full machine again.

Hello @carrcrew,

I never made the write up but the motors come with 2.54mm (dupont) connectors so it hooks up easily to a GRBL shield. Use DRV8825 drivers or better, a fan to cool them, and a 24vDC PSU (250W and if possible NOT for a LED strip, the ones sold by OpenBuilds are good (what a surprise, I brought them in ) ). In the software section of this forum you can find more information on GRBL. When you come to the point finishing the electronics and you need help then just ask; first worry about the mechanical part .

Hello Wassim,


The new machine you are talking about still is in testing but it looks promising. When you go with the Ox you will need to make custom plates. Note that you always have to cut V-Slot to be square and correct length.

Hello Alberto,

Thank you for the complement. There would be one change in the design to make it better; place a bearing between flex-coupling and the Acme rod plate instead of the M8 shim.

I don't have the the settings for the Arduino Uno but it's the same as the original Routy when using 20t pulleys, but if you use 14t pulleys you need to recalculate the steps of the motor. Use the RepRap Calculator - Prusa Printers to get the right value (GT2 2GT 2mm belt and if they are OpenBuilds motors then use 200 steps for 360º (full) rotation). It's recommended to use 1/4 or 1/8 divider on your stepper drivers.

I hope this gets you started.

Hello @gianmarko,

The gantry uses a 20x60x442 and a 20x20x442 V-Slot, the 20x20 reinforces the gantry at the back. This router should be able to route PCB and normal wood without a problem.

I would recommend a DeWalt DW611 or 660 router. The 660 router can be clamped the same way as the Dremel rotary tool but you can buy a base for it as well: DeWalt DW660 Spindle Mount . The downside of the DW660 is that is does not have a speed regulator, so it will always work at 30k RPM; there are cheap regulators on eBay: Universal Variable Voltage Router Fan Speed Control Controller 120V AC 15 Amps … . But you might just skip the DW660 and go directly for the DW611 .

I hope that this helps. Remember that you need to cut your V-Slot straight so be prepared for that.

-Ronald

 

You don't need a tool bigger than 1/8", and don't plunge so much, 0.5-1mm at a time.

The DW660 comes normally with a 1/8" and 1/4" collet, the DW611 comes only with a 1/4" collet. I forgot to add this to the post above.

Take a look at this video, useful when using a light CNC router:

-Ronald

 

The DW611 is a bit heavy on the V-Slot 20x60, but the DW660 should not be a problem. I never tried the DW611 on the Routy so it's hard to say.

I would add more wheels and use a C-Beam to replace the 20x60. I'll draw the modifications/upgrade for you; gantry plates will be the same, but you need longer screws, some spacers and more wheels, besides the C-beam that is.
