Retrofit Approach was created by KPA
As I struggle with my own conversion (2nd one) I see we need some sort of documentation that speaks to the approach to take for a retrofit that incorporates EMC2.

Something like a simple checklist that can be expanded upon, e.g.

1. Assess machine physical state and repair, i.e. worn parts that need fixing, etc.
2. Read ALL EMC2 documentation - 1st pass to get a cursory understanding of EMC2 and the resources available.
3. Scan EMC2 forum topics - to get a feel for current hot topics, other knowledge gems.
4. Determine what you will change - are you improving the machine, reparing it, or ruining it.
5. Put together a functional control list - this is the start of the logic build
6. Pick your GUI, design your Console
7. .. <haven't figure it out yet as I'm still working my way through everything>
8. ..<pick your interface boards, drivers, etc.>

To some this may be obvious, to others, especially folks new to retrofits this will be gold!

There is a broad class of fine manual machines were retrofitting to CNC could be considered a downgrade. If your goal is to maintain the precision of a touch operated machine, then until serious work on backlash, feedback and jitter is done, your defeated before you start.

There is a reason hydraulically controlled machines were/are used in the watchmaking industry.




I'm looking for 10um, or its not worth the effort to spoil a nice machine.

Jay,

Sounds like a good idea, you can add your pages to the wiki which is a user maintained source for information.

JC,
I know exactly what you mean, a retrofit should either repair or improve the machine, not destroy it. I've seen bad retrofits out there where people take a rip-and-replace approach, ending up with a shell of a machine. A lot of good engineering goes into functional design. Sometimes a light touch is all that's needed, i.e. a simple DRO added, or upgrade the electronics. The retrofitter needs to be thorough in his assessment to determine if they can really improve upon an existing design.

I would put an Hardinge HLV-H in that class. Picking up one is in my future, but to retrofit it, not so sure. I know Babbin does them, but they go to a lot of effort to retain original look and feel.

John,
Thanks for the invite, I need to build it out a bit more before I post it to the Wiki.

If anyone has more ideas that apply please post them and I'll compile them into a Wiki page!
