My DELTA-1

I wished to had a machine from SeeMeCNC but simply at the part of world i am living can not afford too many taxes. I am having my home made CNC and following pictures shows my progress so far.. I named it DELTA-1. I dont know whether this thread to be continued or not as this doesnt pertains to SeeMeCNC...

Definitely interested in seeing where this goes!

Looks like you have a pretty good design worked out!

Thanks guys for giving me space in this superb forum. I am going to install magnetic effector arms. Designed the effector plate and CNC machined 2mm Aluminum. I also drilled /tapped M3 holes in the hot end fin part ( don't know the name of it)...

Here is the effector plate with probe and hotend mounted

Also machined some acrylic parts to be mounted on linear rail block

Which probe is that?

Is it contact type?

Is it precise enough?

Khalid Khattak · Post by **Khalid Khattak** » Sun Dec 14, 2014 9:17 am

Teoman, This is inductive proximity probe NO NPN type. I am using the same in my CNC machine for homing and limit... I am using 12VDC to work with. I made a opto-isolater PCB which will work with RAMPS1.4 logic level voltage... These probes have higher accuracy as compared to mechanical type limit switches

The fan mount CNC machined from 1mm Aluminum.

some more progress...

Wow, looks like you're almost done already!

Khalid Khattak · Post by **Khalid Khattak** » Tue Dec 16, 2014 1:28 pm

Thanks Ben.. I am working hard to get it completed but the more i work on it the more things comes out on the way

.. I am doing office work and get little time to work on it as the days are short here..
The better is to get the completely assembled printer...no hassles at all... today did more CNC work..hell of work ahead... dont know how will it goes, how will i calibrate..what results i will get!!!! May be someone here help me...

Khalid. thank you for posting this here, I feel you are adding a lot to the forum because of the different ways you do things.
It never hurts for us to see other methods of getting things done. Thanks again.

Thank you Eaglezsoar for the space you have provided and all that appreciations. You people are really great

Installed the belt by my own way

... was thinking how to lock , how to make proper tension. here is the simple procedure.

Post by **Eaglezsoar** » Fri Dec 19, 2014 11:40 am

A very clever way to tighten then glue the belts together, thanks for the pictures!

This thing is looking good so far. I'm wondering how you're keeping track of tolerances and dimensions on this stuff though, especially since the plastic and wood parts are subject to thermal expansion and moisture warping.
In particular, how did you align the linear rails on the vertical axis? How straight are they, how much backlash, friction, mass, ect.

Either way that CNC routing looks nicely done; it makes me want to make a big CNC router for my own projects!

Khalid Khattak · Post by **Khalid Khattak** » Mon Dec 22, 2014 3:20 am

Hi Generic Default..look at my CNC router 5ft x5ft..its amalgamate of wood, steel and aluminum.... i have experienced machining of wood, plastic and Aluminum with it with close tolerances.. If this big machine can provide tight tolerance then what about the smaller 3D printer... I hope i will get good accuracy too but again time will tell...

i made the jig to align the linear rail...

Spool holder drafted in CAD ready for CNC machining out of 8mm MDF..

Khalid Khattak · Post by **Khalid Khattak** » Mon Dec 29, 2014 9:43 am

Finally machined the spool holder..

teoman · Post by **teoman** » Mon Dec 29, 2014 9:50 am

Should have entered that spool holder to the christmas decorations competition

Khalid Khattak · Post by **Khalid Khattak** » Mon Dec 29, 2014 2:23 pm

@teoman..didn't think of that

... and i got the magnets from Dart games... These are assembled in metallic casing and the good thing is that the back side of casing has M5 tapping...

BenTheRighteous · Post by **BenTheRighteous** » Mon Dec 29, 2014 3:49 pm

Very clever source for the magnets!

Khalid Khattak · Post by **Khalid Khattak** » Tue Dec 30, 2014 8:21 am

Thanks Ben...

I got 6mm tubing, tapping M5 at both ends. I am using M5 bolts (This helped me adjustable lengths) with the arm. The attached pictures speak itself... Now i need two things:
1- Making spherical ends for magnet out of teflon or some PVC..don't have 3D printer to print them out

2- Calibrate the printer

May be i have to replace the steel tubing with something having less weight..still needs to sort out...

Wow, well done sir. Thank you for sharing!

Khalid Khattak · Post by **Khalid Khattak** » Tue Dec 30, 2014 11:13 am

thanks timothy.... Finally Its Alive without any magic smoke.... Now requires tweaking,alignment and calibration... Needs to resolve minor issue with one of Axes motor (adjustment of current at Y-axis motor)..need good Cable management... .. Still way to go for actual printing...
