the 3d table is made by isel, so I think it is mechanically OK.
I looked at the motors today, and they are isel model
473030, with a torque of 110 Ncm, 2,8V / 4.0A Bidir.
I used a dremel tool with a 3mm mill for milling in MDF.
as I said earlier, using this setup and a program of my own to
drive the table it was constantly losing steps so thats why I
thought feedback would help

experienced guys: can you tell me if milling in mdf and/or
aluminium should be possible with this kind of table ?
is the simplest and best solution for this to just drive the table at
slower speeds? (I did some rough calculations, and with slow
speed the milling of a 3d part(ca500x150x20mm) could take
many hours: 5-10h! with a slow speed, is this
common/acceptable?)
