Deltron and Meccano Marriage

Deltron and Meccano must have had a marriage some time ago without us knowing.

 See the following:

 I wonder when was Deltron actually founded?!

Monitor Mounting

After some re-organization and clean up I decided to slide the PC behind the printer and mount an old monitor to the machine.
This is how it looks now:

Took some 20mm X 150mm strips for wood framing brackets and bent the ends into hooks.
End result is :

Nazdorovia!

VAT-Frame correction

I have missed something during the VAT-Frame build. Someones sharp eye pointed it out.
Between the U shape profile VAT base and the L shape sides of the VAT frame there are small screws that protrude.

It is a set screw with a M4 collar. It is used to set the VAT to be parallel and at a specific start distance from the build base.
This is what it looks like only smaller:

The inside diameter is M4, but the screw itself is M2.5 thread. The bolt is 30mm x M2.5
Sorry! and Thanks for pointing that out.

L-Bracket for build base

Scored some 80/20 L-shape brackets. Finally! Four pieces to be exact.

I bought some M8 bolts too. I can start the Build base tomorrow.
Wish you have a great build day!

3DLPrint X and Z Test

The title does not give it all away, but the following does! :



I'm running the X and Z without limit and home switches, but have been around enough to be confident in my abilities. Your mileage may vary. If you do not know how to operate CNC machines safely , I suggest you get someone who does, to do it. If you do not know how to be safe around electricity, get someone who does, to do it.

The cycle is:
1-Go to Bottom  ( X -5 )
2-Go to TOP ( Z zero )
3-Go to work coordinates of Z zero - 10.
4-Slowly move to Z zero ( the last 10mm )
5-Slowly raise to X zero.
6- Display slide and display black screen
7-Go to X -5 then Z- (10 times the slice thickness )
8-Go to Z zero and then X to zero.
9-Repeat.
The first 10 slides are for the Base of the object to be printed. The rest are the object itself + supports ( if any ).

I'm sure it will create a stir!

RTFM I always hear - Stepper Drivers

Yes! I have read it and it is much easier ( even easier if you have used IMS drivers before ).
A little bit of temporary wiring to make sure the Stepper drivers even work.

Make sure you read the manual of your stepper and calculate the max Amps per winding. If it is nor marked use V=I*R and solve it for your own case.
After that a little housekeeping and tidying up the wiring:

All is working! Meaning - no smoke came out of anywhere and nothing smelled funny.
Be safe around electricity!

X-axis mounted

As you know I'm using the DELTRON Linear LRS3-1. It is wider than the Bosch frame ( 40mm ) and it is not in the center of the printer. I have mounted it with only two of the 4 bolts.  Loosen the two nuts and slide the X axis extrusion straight down. Clamp you slide and mark, and drill your pilot holes. Drill with 4.5mm drill bit and tap with a 5mm thread. I used a 20mm Inbus to bolt it to the extrusion and fasten it to the frame.

Ok, I'll do this  to save another post with corrections:
I replaced the motor that is in the above pictures with another I had on hand:

The reason being, that last night when I hooked up the stepper drivers it was underpowered and stalled after numerous attempts to tune the motors. Also after a brief period of correct tuning I tested  some macro in Mach3 and the motor got very hot, very quick. So it was not meant to be.
The new one performed perfectly right off the start.
