Hi Jezz and thanks for the reply.

The gentry is made of 100x100x4 mild steel mainly and 20mm aluminum plate.

The estimated weight of the gantry excluding the steppers/HIWIN rails and blocks/ ballscrews and mounts is:

Y + Z = 135 kg (including 5.5 kw ER32 spindle)

Z = 46 kg (including 5.5 kw ER 32 spindle)

In terms of speed I have no idea to be honest . I was told by someone who used to machine ice that I can push it as fast as I can as is really easy to machine. I guess experimentation will tell.

I was thinking of servos as well, but they need gearing and since planetary gears are expensive and belts aren't an option in the freezer I think I am going to stay with the closed loop hybrid servos.

I have seen your video review of the similar system from zapp and was quite impressed.

Please see the attached pictures for sizes.

Light Grey = 100 x 100 x 4
Dark Grey = 150 x 100 x 4
Orange = 10 mm steel plate
White = 20 mm aluminum plate
Blue = ice
Purple = removable module to be replaceable with 4th axes module in future
20mm HIWIN rails an all axes
