Just wanted to share my experience while upgrading the Y-axis drivers with high power digital driver from stepperonline. These are the DM860T and cost about $45 each on amazon. I thought I would try them instead of spending more with driver that Langmuir offer at twice the price.
Here there is a video I took for the full process, including some issues and troubleshooting. They seem to work great in the end, at least from few simple test movement for now.
THe video is a bit long, but might be very useful to those that like me, wanted a step by step instruction. I decided to pull the trigger so others could benefit from my experience.
Comments are very welcome.
