Prusa i3 direct drive new build (3 replies)

Hello all. I have been building a Prusa i3 with Wades extruder over the past few months. I will try to post some pictures later, as I am at work.

The following will describe some of the configuration.

The printer is using a sanguinololu 1.3a with Kliment firmware.
-- I will be changing the electonics into a ramps 1.4 setup soon, but I am waiting on some new parts.
A4988 stepper drivers with NEMA17 motors for the X, Z axis and extruder
-upgrading to drv8825 steppers for for current capacity
one NEMA23 motor for the Y axis with a direct drive and m5 rod
-In my firmware, I have configured the correct steps per mm for the Y axis


I had this sort of running, but had belt problems on my Y axis. I have since decided to recently convert the Y axis into a direct drive setup.
- This was due to waiting for a puller to remove a gear on a nema17.
The Y-axis motor works most of the time, however it does not always seem to have enough current, and without the rod connected, sometimes stalls
-I think that this is due to the replacement motor having ratings for up to 2.5a, as I cannot put the drivers voltage higher

My current questions is could it be that the acceleration for the axis is to high, causing missed steps? I would like to try other options after my work day is over.

Thank you.
