I'm currently in the planning/ordering stage of my build of a new controller box for the 3020 CNC router/printer. I've been looking around for motor drivers and there are a lot of cheap options and some expensive options. There are not many good options in the $20-$40 range. Gecko drives are of course always ideal, but $100 per axis is out of my budget. I have been hunting on eBay for a while and have previously posted on the notorious
HY-DIV268N-5A. In my eBay searches I also saw a few drives that looked similar the the HY-DIV268N-5A, but had are rumored to have performed much better. I wanted to try them out!
They appear to all be based on Leadshine and rebranded into at least two other names, Rattam and Wantai.
Rattam Motor RTM5740A
Price: $25
I have purchased 4x RTM5742A drives and plan to do some analysis of the hardware. I hope to get a good idea of the quality and share this with you.
Based on the ON Semiconductor LV8727. I have sadly found that there are several other boards based on the same IC for much cheaper, some as low as $10 each. Just search for "DD8727v1" on google or eBay.
To be continued....
