Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
I see it calls for a 5V customer supplied 1 amp power supply. Is 1 amp enough for three DYN4 drives. Thanks

I always thought it would take longer to grow old.

Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
Is there going to be a problem with the mixture of the two drives ,i have DYN2 and DYN4 drives ?
I also have a question about the limit inputs if using proximity switch, as you have daisy chained the input for the DYN 2 drive.

Others, including myself have had noise issues using the internal 5 volt supply. DMM recognized the issue and has recommended using an external supply.

Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
I have a question on input 2 with a DYN2 drive, wiring says ZRI or absolute zero position index ,what do you set it to in the Wizard?
When i selected Dmm Tech it set it to 2nd limit.

Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
You do NOT set anything up in the Wizard.
Are you planning on using the ZRI for homing?
What kind of machine are you working on? Lathe, Mill?
The theory is (mill),
You series all your limit switches together, one lead goes to common, the other goes to input 1. Select HOME ALL in the Wizard.
You set input 2, 3, 4 to UNUSED in the Wizard.
You connect the ZRI from X to input 2, Y to input 3, Z to input 4
The software still sees the inputs. Its simply watchig for the state to change on the input, when it does, it stops and sets that axis to home.
Credit goes to Scott Pratt, the Great Wizard at Centroid for working with me to coming up with the home file:
There is a custom cncm.HOM file you have to make up for example:
M92 /Z L1 ;Move to Z+ limit switch, back off until it clears.
M105 /Z P-4 F1 ;Move Z minus at 1ipm until input 4 closes
M26 /Z ;Set Z home here
M91 /Y L1 ;Move to Y- limit switch, back off until it clears.
M106 /Y P-3 F1 ;Move Y plus at 1ipm until input 3 closes
M26 /Y ;Set Y home here
M91 /X L1 ;Move to X- limit switch, back off until it clears.
M106 /X P-2 F1 ;Move X plus at 1ipm until input 2 closes
M26 /X ;Set X home here
Save a copy of the .hom file to another directory because if you run the Wizard after creating it, it WILL overwrite it with the default .hom file
I just posted a video today demonstrating using the DYN4 and the above .hom file
I have previously posted one for the DYN2. The info is buried here in a post. Search DMM DYN2 or DYN2

Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
custom home files are probably out of the scope of the wizard. i'd say we just start posting a collection of them here.
starting with the ones you have worked on. DYN2 Lathe, and DYN4 MIll. how about posting the cncm.hom and cnct.hom files for both?

Re: Updated DMM DYN2 and DYN4 to Acorn Hookup schematics.
I updated the original thread:
viewtopic.php?f=60&t=1233
I agree, too many ways to do the .hom file depending on the machine.
I think simply, is a way to turn off the Wizard creating the .HOM file. Perhaps a radio button to turn the option on/off?
After all the work creating the custom .hom file, all it takes is one "Write to settings" afterward and its....gone....
