Double Sided, No Plating


(Some common errors and solutions are listed after the process steps.)

Before starting, make sure:

Step 1: Process setup and first drilling on the ProtoMat

Step 2: Etching with the ProtoLaser

Step 3:Routing with the ProtoMat


Common Issues

First, make sure the ProtoMat hardware is on; if it's on already, there will be a red light under the toolhead (for the camera), and the status light on the toolhead should be at least blinking green. If it's not on, turn it on by toggling the green switch located underneath the cover, to the right of the working table, above the main power cable. Once you've confirmed the hardware is on, in the software, in the main toolbar (with the File menu), click “Machining” > “Connect”. Make sure that “S103” is selected in the dropdown menu and click “Connect”. Let the connection process happen, and then try the fabrication again.

You probably forgot to assign it a layer. If this happens, the software will put the gerbers onto their own layers that are named with the gerber's name. Try re-importing the files, and make sure you’ve assigned each file a Layer/Template (see figure 11). Also make sure to delete the incorrectly-generated layers (right-click and select “Delete”).

You likely forgot to import the drill file. If so, you'll have to restart the project over again. Sorry. Alternatively, the tool may have failed to pickup the bit correctly. In this case, come find a PI.

Stop the process as soon as possible, if it's still running, even by lifting the lid. Go get a PI. If they don't know what to do, ask them to message our Slack channel.

There are a couple of possible reasons for this.

  1. You may not have imported the drill file or the board outline gerber correctly.
  2. The bits in the magazine may have been incorrect.
  3. The tool may have done something silly.

In any of these cases, there is no good solution other than to restart the project and double check all of these (if possible) before starting to re-process. Sorry.

It’s likely that you either did not save at the correct point in the process, you saved over the pre-toolpath file, or you are trying to import the wrong file. Double check all of this. If you’re certain you did it correctly, get a PI.

Sometimes, when placing the board, the fiducials move in the opposite direction as the board. This is a known bug! You can either: try estimating the location of the fiducials and starting the process; start a new document; restart the software; or restart the hardware. (The latter two require a fresh 20 minute warmup for optimal performance.)

You can either restart the process entirely (hit the Play button, see figure 32) or right click on “Top Side” (or “Bottom side”) under “Processing” on the left, and click “Process from here” to restart the top (or bottom) side processing with top (or bottom) side alignment. Do first check to see if you can manually remove the strips, either with a scour pad or with a microscope and tweezers/a knife. It's usually faster, and less likely to ruin your board.

On the left of the screen, make sure nothing is selected under “Processing”. If there is, hold down either CTRL (on Windows) or the command key (on Mac) and then left click to de-select it. If that doesn’t fix it, you can select either “Bottom Side” or “Top Side” (again, on the left) to force the correct orientation. You can try starting the project over again if this doesn’t solve it as well. Sometimes, the software has bugs.
