Hey Mike, are you using longer screws for the nema8 ?

[Mike M.]

Yes Jim correct - but out of 4 two are needed only for preventing stepper to turn

Mike

[Mike M.]

Jim you are missing Nozzle holder and vacuum fiting (Aliexpress with screw sealed)

Bottom belt pulley are only 2x flange bearing ID2.5 OD6 x 2.5mm on a M2.5 bolt - no pulley needed

see enclosed

Thank you, Mike. I was just curious how it works.

[Maple_Dude]

Clever to use the bearings sans the pulley

[Maple_Dude]

How do you like it so far, now that you have had it for a little while? 

[Mike M.]

Hi,

Not in operation - need to change Cable chain (it has no space for additional cables needed for this head to operate) few otrher things to change on my working machine need upgrading as well, I am in no hurry.....

You might put [a|the] controller on the head, as has been discussed in this group.

Hi Mike,

Are you happy with your 6-axis setup?

Have you already done some boards using all four nozzles?

[Mike Menci]

Hi Marmelade, 

Yes my 6 axis do work fine - still some final tuning to do (on Z and A to equal level alignment, ...) but I am not in a hurry abecouse I do not have a PCB project to push me to work on it on PnP.... I get my PCBs with partly assembled (PCBA) parts from China, and I do not need to play with solder paste and stencil at home....

Mike, 

what feeder system are you using ? How your feeder works?

All i see on openpnp website plastic feeder 3d printed. I dont wanna use them..

Hi Nick;

I do not use plastic feeders where did you find that ?

https://www.youtube.com/watch?v=pqw5Q8BhUz0

On Left side of the machine I use DIMA feeders (for parts larger than tape size 12mm) - actuated by 1 digital servo.

Because of DIMA feeders my 4 nozzles are not in one line but 2pcs per X line in Quatro arrangement.

On right side I use Schults Siplace feeders with this Schultz controller https://github.com/bilsef/SchultzController

I use only one smoothieboard for running X servo, Y servo, Z Nema14, A Nema14 and 2x sharedC 2x Nema8=4 C1-4.

I hope this answers your question

Mike

[Nick]

ok,, Thankss 

I guess u misunderstood me, i was referring to openpnp website.   

Anyway these feeder looks great and compact.  Any performance issue like tape skipping etc...

Just curious about structure to mount these feeders. where i can see design files

Cheers

My PnP arrangement can be seen here: https://grabcad.com/library/pnp-machine-3

I purchased feeders 2nd hand - and fixed them - in addition to Siplace Schultz feeders you need Bed Base Plate which will hold tween feeders 31mm apart

and in line + Connection distribution pannel where you connect each tween feeder to Schultz controller.

ebay item : https://www.ebay.de/itm/Kommunikationseinheit-fur-Siplace-BE-Wechseltische-S-F/324098011705?hash=item4b75bf3239:g:OS8AAOSwcMNeZk~8

or you can make it yourself like I did - see Cad above!
