CPM Series

Desktop CNC milling machine, in three sizes.

The CPM series are machines
that any company can afford,
to do in-house Rapid Prototyping.
The work-area is large enough for most jobs, the operation easy and the price unbelievably low. The CPMs are designed to machine all non-metal materials.

The CPM machine is no longer in production, so we cannot offer these machines for sale anymore. It's successor is the ICP machine.

What we nevertheless still can offer is an option to improve the speed of a CPM machine. As thousands of these machines are still being used, this Booster card option (see below) may benefit many machine owners.

Three models of the CPM have been produced: CPM 2018, CPM 3020 and CPM 4030. All three had a cover that could be opened by rotating the door upward: see the illustration above. All CPM machines were delivered with the IMC4 stepper motor controller inside.

The older ICP models with a IMC4 controller can profit from this Booster card as well.

At our website www.deskproto.com a few videos are available that show a CPM machine in action !

The CPM Booster card will greatly improve the performance of the IMC4 controller that is used. So this card is great news for anyone who owns a IMC4-based machine like the CPM (and thousands of these machines have been built): with a small investment you can double the speed of your machine and also improve the surface quality of the resulting parts (the actual time gain differs per NC file, and will vary between 0% and 80%).

The video below will show you the difference between the original machine and one with a Booster card installed.

The CPM Booster Card is a plug-in card for the Isel IMC4 stepper motor controller.
The card supports advanced kinematics that allow the machine to keep up speed while moving (where the original IMC4 briefly halts between every two movements). A look-ahead function will decelerate only when needed.

The video will first show you an NC program file executed on a machine with the original IMC4 controller. When you have such machine you will recognize the typical staccato rumbling noise made by the machine.
Next the same NC file is machined again, but now on a machine with the Booster card installed. The different movement style is immediately clear: you will both see and hear the enormous improvement.

PDF manual   Download the CPM Booster manual (English, PDF ca 800 Kb).

The manual includes chapters about the card, the hardware setup, software setup and how to operate the system. In addition three appendices provide background information on CNC Control, Card settings and Card specifications.

The price of this amazing card is euro 490.
The card comes with complete installation instructions (see the PDF manual).
Note that you need to have the KAY control software in order to use the Booster card.

Please check: the card cannot be used in some VERY old CPM machines. In the controller two Eproms will be replaced by the Booster card. Some very old IMC4 controllers have Eproms (the chips with the white label on top) with 2x14 pins, the booster card needs Eproms with 2x16 pins.
