Meldas 320 on a Mighty Comet Spindle Parameters

A local guy has a Mighty Comet 1000 here for sale, but it has a problem and before I even entertain the idea of buying it I wanted to see if it was something I am even capable of resolving. According to the seller the machine was stored for so long that the batteries died on it and the system lost its parameters. Apparently they got the parameters from Mighty and, I forget if those parameters got the axises running, or if those weren't affected to begin with, but the spindle will not turn on nonetheless because they apparently do not have the correct parameters for it despite what they were given by Mighty.

I have no experience with this controller or machine, so I'm trying to figure out if this is a common problem that can be remedied with some advice and a parameter list, or if this is something that requires someone well versed in the controller and/or machine to take care of.

I've poked around the web as best I could and was not able to find any specific info relating to getting an inoperable Mighty back online after it lost its parameters due to battery failure.

Does anyone know enough about these machines or controls to know if this issue can be easily resolved or am I on a path down a rabbit hole? The only reason I suggest the latter is know there can be issues getting support for these machines from the vendor.

Thanks.

Comet really is Hartfold
parameters attached
also somewhere on this forum I uploaded macro for tool changer

Thanks for that attachment. The only problem is after reading all of those pages I'm thinking I'm biting off more than I can chew, because despite developing software and programming microcontrollers for many years it kind of makes my head hurt thinking about trying to confirm all of that and it looks like there is a lot of ways to screw things up and one way to make it right. When I heard the spindle params were lost I was thinking a handful of entries, but that is a bit more overwhelming than I was hoping it would be. I'll see if I can make sense of how to get the reprogram the controller and see if the owner wants to give it a shot but otherwise I think I'll pass on it.

if you want we could get that machine to run together
just PM me if you agree

Hi Guhl,

I have tried searching for tool change macro for the VMC-1000 Meldas 320 you mention, but I cannot locate it, please repost or email it to me PLEASE!

Hi Guhl. How are you? I'm a CNC Tecnician. I'm working on a Ecoca lathe. And I don't have plc parameters. Do you know how to load r1900 plc parameters?

Can I Download the plc program to a PC?

Thanks so much

Carlos Cabrera

what parameters do you need?

Hello guhl. I see you have quite some knowledge in these meldas 320. I will much appreciate it if you could help me now how to upload parameters to the machine cause my battery died. I already got the machine parameters from citizen. The machine is citizen L16 from 1993.

Can I have it please?
