If i build it, can any software put gcode together for it?

Perhaps crazy overactive mind question... looking at routing pcb's again - has been getting expensive sending them out to batchpcb etc,...

Controller for sure, but there's better than 6 gcode interpreters already done, so no point redoing that - likely will just use grbl - as its pretty much setup for thi....

If I do loose my marbles...

I'll have to look - but last I played, those were a bastardized setup to begin with - great for transfering one way, not so sure about bi-directional.... Pretty sure I'd have to go for the full on...

Yeah, there's going to be some compromises - always are...

I'm using the freeduino sb - atmel328 so I'm starting with 32k of flash and 2048 of sram; gotta support the local suppliers.

Kicad

Kicad is open source, all the features of eagle, all the eagle libraries have been converted... I find it much easier to use personally.

Lots of projects kicking around to do test runs...

65v will be a problem, I'll poke around a bit, but most DIP package h bridges max out at 48v... The SN754410 is a 36v max, L298 Could be easier to heatsink - and is up to 48v - but could only handle...

G'day all,

Perhaps some colaboration will drive me to a better more universal design... Throwing this together in kicad anyway - perhaps others will want to build it too...

Tired of LPT...

Honestly the grblshield interested me, but ... By outward appearance it's just 3 of the reprap driver boards mounted on a nice shield format... That A3892 is the only headache, SMD components don't...

Probably something like that - haven't tried digging into the melted mess that is the power supply, likely just going to toss the works into the trash today, nothing left worth salvaging... and its a...

No loose wires thus far - looking like the power supply must be the culprit... looks like it probably fed something way over - as the drivers on the hobbycnc are no longer there... tracings have...

Was looking for some inspiration for the rebuild, wanted something a little more space friendly for a desktop CNC build... Ran across this one, which has those gears in my head turning, and maybe...

Yeah, no people hurt, still stinks of electrical fire in here... That's the important part...

Looking at putting an arc fault interupter onto the CNC's power circuits, though that might require a...

(chair) Never let the CNC run unattended...

Not sure what happened, But lost all my electronics last night... Cutting parts to build a RepRap Prusa, things were going good - so I decided family...

Yep, all steel flexes, all buildings flex.

There's a big difference between a 20'- 60' span and an 18" span though. The loads to acheive any substantial flex across 18" are insanely high in...

Excuse the poor rendering - still learning this magic cad/cam stuff (Never saw the point until this past year - pretty pictures on...

Yeah, HSS has various meanings - I'm in construction, I deal with both HSS daily and can use both terms in the same sentence without thought; generally assume others do also. Possibly my fault on...

Hollow Structural Section... Chances are if you look around a commercial building you'll see a lot of it used - it is your basic structural steel you may alternatively know it as c-channel, i-beams,...

Routers actually small - cutting area will only be 12x12, built out of 3" x 1/4" channel. Dual 1" acme's on the x and y (had it lying around...) Still working out Z - partly depends on tool(s)....

Now call me nuts - but using the correct tool (spindle, drive, whatever you prefer to call it) + the correct bit... One would be able to cut steel no?

Why I'm asking about tools and bits... I...

Hey folks,

Please don't take this as blasphemy... or come after me with (chair)

Looking for a tool recommendation, building a fairly typical moving gantry router. Construction is HSS steel...

I was commenting on the delamination problem more as a cautionary notice... This isn't aircraft construction we're doing here with carefuly regulated materials; there's a huge difference in scale - a...

In theory it would work well - as a reinforcement. Injected polyurethane is used to strengthen (and insulate) in many applications these days. A lot of the construction we see of late uses these...

Yeah, Somehow I dont see being able to use the same tool for cutting acrylic and steel... Possibly if I did a true spindle type mount - with some radical gearing options between the motor and...

Hey folks,

Couple questions about design for those who know this stuff a bit better.

Still in the design phases of a 12x12x4" moving gantry router, HSS construction (Its what I know, have and...

Anyone able to point me in the direction of some plans for a steel based CNC design? Spied a few on the forums, but none with plans available, mechmate doesn't look like it could be scaled down...

Yes, it probably would work - but it's no fun buying something pre-assembled. Heck, it's probably cheaper than a DIY version too.

I'm not overly fond of the fixed gantry myself (though I'm sure...

Hey folks,

I guess my CNC router needs are a bit different than the rest of you - judging by the size of your designs... I've decided a 12"x12" (cutting area) CNC router table is high on my todo...

I've been looking through the 8020 catalogue all evening (pablo - you're a bad influence!). Had a question...

Is there any reason one couldn't use the 'off the shelf' linear bearings from the 8020...
