MultiCam Classic CNC Router

The MultiCam CNC router is capable of cutting and engraving up to 5x10' sheets of wood and plastic. Training is required in order to use it.

Materials

Basic users may only cut wood on the machine. Advanced rated users may cut wood and plastic, and may engrave many materials with the diamond drag bit.

Training

There are currently three classes being offered for the CNC Router at various times during the month.

Basic CNC Router is approximately 4 hours in length, and has a $50 fee. This fee helps pay for replacement bits and machine maintenance. After the class, a hands-on test must be scheduled before unsupervised use of the machine is allowed. This class enables users to cut wood and products made from wood.

CNC Router Hands-on is a workshop intended for new users to get some additional hands-on experience prior to taking their test for the Basic CNC Router class. The class is limited to 5 persons.

Advanced CNC Router is offered only for those who have already earned their basic rating, and gained some experience using the router. Topics are discussed to allow users to become more proficient using the router, and to enable advanced users to cut plastics, as well as using the diamond drag bit.

User-supplied Cutters

If you choose to provide your own cutters (bits), here are some options:

  • Onsrud - particularly for mills, compression bits and ballnose (Onsrud is frequently available through Manson Tool)
  • Freud - particularly for Vbits and tapered ballnose
  • Other popular brands include Amana, Misenheimer and Niagara Cutter plus these online sources:

Infrastructure Setup

The MultiCAM computer in the woodshop is a Raspberry PI remote connecting to the Jump Server.

The Jump Server has software that supports the MultiCAM.

"Machine Tools Suite v4" is required to be running on the Jump Server for operation. This software has a required USB dongle on the VMH-07 Hyper-V server.

The software can be downloaded from MultiCAM Downloads and it is called "MultiCam Suite 4 Install"

VCarve Pro is also installed to support the MultiCAM. If VCarve can't find the license, see this Talk Post for troubleshooting.

MultiCam Special Interest Group

SIG Leader: Bert Rabbe @bertberaht

The Multicam SIG category is a place for SIG members to communicate ideas, tasks and status of projects related to operability of the CNC Router.

The goal of the SIG is to identify appropriate consumables inventory, modifications, and preventive maintenance tasks, then document same, and develop a staffing/implementation plan that will optimize the Multicam CNC Router in keeping with the needs of the Dallas Makerspace membership. As changes are made, the SIG will develop secondary training for members as situations dictate.

At the present time, the SIG scope does not include design software issues and training which is currently handled by qualified instructors.

SIG Information

In January 2019 the SIG (with the assistance of numerous Makers) repaired the Republic blower and modified the CNC Vacuum Holddown Bed. A status update was prepared for email distribution to authorized Multicam users.

A copy is also available on the committee drive:

Operational Notes and Videos

Spoilboard and Hold Down

  • Vacuum system is partitioned into active zones
  • NO SCREWS in the spoilboard
  • Video 1 - 2019 update to the spoilboard, zones, and hold down (07:40 min)
  • Video 2 - Alternate work material hold down approaches (05:35 min)
  • Video 3 - Hold Down Helpers. When/how to use the new helpers in securing your material. (02:06 min)
  • Video 4 - Spoilboard Repair (how to) (05:40 min)

Setting Z Height

Fasmer Method is an alternative way to specify both top and bottom of material in one step. It is a great way to minimize issues with cut through or leaving onion skins.

Dust Collector

MultiCam Dust collector MT warning
  • It’s time to “MT” (empty) the bag when the lights turn on.
  • The bag sits on a seesaw platform. The bag sits on one end and the magnets are on the other. When the bag weight exceeds the magnetic force, the seesaw will reverse.
  • Please shut down the collector, empty the bag and reinstall or replace bag depending upon condition.
  • You may need to manually raise the platform under the bag to reset the system.

Multicam Regular Maintenance How-to's

  • Grease machine: There are a total of 12 nozzles that need to be greased with the long, black grease gun that is located in the MultiCAM desk. There are: 2 nozzles on the left side of the table, and 2 on the right (Where the giant gantry is). There are 4 on the left side of the spindle, and 4 on the right. In order to grease these nozzles, insert the grease gun gently onto the tips of the nozzles. Make sure that the grease gun is set directly facing into the nozzle and gently press the gun's handle to extrude the grease. Do so until you visually see the grease come out the gantry, then stop immediately. Do so for all the nozzles. Lastly, move the Z-axis completely down and use a spray can of white lithium grease to apply to the Z-axis/vertical extension gear above the spindle. Move the Z-axis fully up and repeat the process on the bottom half. Wipe off excess and residual dust around the vertical gear. You are now complete.
