Primus W-10X^2 update "I need Control!!!"

[supremewhirlpol]

Pete,
The motor in the Primus W-10X^2 weighs 105LB. On the day that I welded the mounting brackets, moving that motor back a forth did get very tiring. But I suppose for me this project would not have been as interesting if I did not have to put in any physical labor. I have to say that that motor is heavy, but heavy is GOOD.

Lee,

Your control PCB looks very nice. Did you use a FPGA for your program? That board looks like it was professionally done. What controller chip are you using?

British cycle codes

Hi Lee,
it's a pity that British labelling codes for garments are no more used as a standard code everywhere ...

I can see a boilwash (1), a 60°C cottons (2) , a 40°C cottons (5), wool (7), separate rinse and spin, separate spin.
What's that full circle key over the (1) for ? Maybe to switch cottons ---> minimum iron ( 1->9, 2->3, 5->6 ) ?

Hi, Supremewhirlpol

I’m using a Microchip microcontroller PIC16F872 and programming it using microchips MPLAB IDE software with code basics I picked up in a book called PIC in practice by D W Smith, so it’s all my design and how I want it to work, well one day maybe. Most of the bugs are the intermittent spins, got the wash right and the heating cycles good as well.

Hi, Favorit

That full circle is the reset key, which has been a god send as the programs have bugs and some times need to stop it quick. I never intend to put the others on 3, 4, 6, 8, and 9 as I have never used them and asked people which programs they used the most, which seems to be 2, 5 and 7. I also think it a shame the old codes are gone, so ease the old dial a fabric.

Liberator and Zanussi

Thanks Lee for pointing it out.

Another question : once I saw in an old thread a Liberator that looks somewhat like a Zanussi, but it makes no sense, at those times Hotpoint had a plant in Llandudno .... what's that ?

Hotpoint 95622,

What language is that? Are you using relays as well? I plan on using SSR's.

Hi, Yes zanussi did make some of the liberator range badge as Hotpoint, as for why, I suppose it was to do with supply and demand; Hotpoint could not make enough units so contracted some out to zanussi. If only I could find an original Hotpoint liberator deluxe.

Language, it’s microchips own instruction set, I’m no expert, learning from books as I go along, to be frank I am amazed that it works to any degree a bit trial and error. Using relays at first, as my skill improves I will swap relay for SSR’s and hope to construct my own speed control board, must walk before run though. Also have plans for a board with a time line indicator on.

Wow...that's gonna be fun to drive. Custom wash-it-all! Does anyone ever remember a commercial machine that was called a Duplex? I saw one in KC in the early 80's, it was a frontload machine with only two baffles in it, nice reddish-coppertone color to it as well. Never have been able to find anything more about them.

Zanussi made Hotpoint Liberator

The Zanussi Liberator was manufactured after a fire at the Hotpoint factory caused a cut in production.

Yay!! PLC cards and DeviceNet connectors have come in!

 

[rollermatic]

now you can take a break

from those exams you mentioned and play a bit!

Pete,
I had so much fun with it that I broke one of the welds for the motor support. The cabinet has to come off again!
