My diy CNC router

[dex918]

Hi guys,

I am new in this forum. I have built my own cnc router. I design it based on reading from cnczone. It's moving gantry type. Working area approximately 18inch x 16inch for X-Y, 4-5inch for Z.

At the momment, the machine is only 50% completed. The main structure is up. I am now waiting for the linear guides for the Z axis assembly, ballscrew and stepper motors.

I estimated that the whole machine will weigh about 60-80kg.
But nevertheless, it's good for rigidity and accuracy. I wouldnt want the machine to end up on the floor while it's doing a rapid motion during operation.

I am now sourcing for stepper motor. Preferably used one with high torque. Maybe 220-250 oz-inch. I know Sim Lim has lot's of electronics shop but I don't know if there is used stepper motor available. I dont mind buying a new one but it all depends on the price tag. Does any of you guys here have the source to purchase online from SG?

that looks amazing so far dude!

Wow! I salute you man. how about posting some links with your plans? I'll be glad to take a look also

[dex918]

hahahaha... thanks guys..
at the momment the plan is not documented yet. I use Solidworks to model it and it came out the same... i have some pics here

[genexis]

Haha nice! Now i'm itching again
So many things i want to try... so little time ..

[dex918]

genexis,

boys will be always boys... and busy with their toys...
So, do you know where can I buy stepper motor online from SG?

[genexis]

no where
Order from overseas...

I'm using the stepper motors from http://www.kelinginc.net/
motor board is from xylotex, 3 axis.

hmmmm... looks like I have to go to SG to find it... hahaha
Do you mean that in SG also cant find those automation junkyard shop??

I think my friend said there is but not sure where lah...

BTW, you work looks good...

I also thought abt kelinginc.. but I will still try to find locally or SG.
I plan to use the PICstep or the pminmo driver.

From you site, I saw you are using laptop. What program do you use? Initially, I also plan to use my laptop but there is no parallel port. Are you using the pcmcia-parallel port?

I saw it somewhere in the local computer shop but I am not sure if I can use it with Mach 3. I plan to use Mach3 and Master Cam.

[genexis]

there is one... at sim lim tower. Lots of stepper motors there, but i think that it is better if you get all 3 of the same specifications. THe motors there look really old and rusted.

Thanks for the compliment on my site

I think my laptop ibm t43 may be the last generation of laptops with parallel port. I'm using it for my cad + cam. Using mastercam + mach3 also

I read that the only way to use the parallel port for CNC is to use PCMCIA.

Great work

I suggest you consider kelinginc stepper motor. The price you paid in SG junkyard can get you new one from kelinginc.

Jus curious you machine those big block yourself or you get ppl to made w conventional mill?

Cheers

Hi Mike,

Thanks for the compliments... anyway, just in case you didn't read my blog (not much of info maybe)..

All the alloy plates are 15mm thick. I have to settle for 5083 series to keep the cost low. My friend who runs his own machining shop help me to machine the parts according to my drawing. But not free.. I provide the materials.

The link between the front plate and the rear plate is 40x40 alluminium profile.
The top plate (work piece table) is not ready. Will be using 18-20mm thick.

I use ABBA Tech linear guides.

As you can see, I also designed the leadscrew/motor mounting block. I use double row angular contact bearing for the leascrew. Why dont I buy the ready made mounting block??? hmmm... it's too expensive for such small thing and it's not using angular contact bearing.

I have not finalised the lead nut design yet as I am still deciding between Acme screw or ball screw (dang expensive!)

Great work bro, how I wish I can own my own CNC....but my programming code had return all back to the lectures...akkakakaka

Sometimes seeing u guy create ur own thing using cnc makes me drool for it..

Update.. without pictures.

Today, I collected the linear guides for the Z axis. I also have to exchange 1 of the linear guide for the Y axis since it has a problem of being "sticky". It does not slide smooth enough and causing a bit of unnecessary load. I am lucky enough that the sales guy agreed to replace. Afterall, it's still new.

Later, after work, I will be fixing the Z axis guide and will take some pictures..
