Introduction The biggest advantage of the GBRL controller based on the 328PB chip is it’s ability to produce 16 bits PWM at various frequencies. However to harness that feature you need to understand how to program it. The problem of understanding and programming the 328PB lays in it’s multiplexed structure. There are not enough registers […]
This page describes how you can get started with cutting and engraving. We assume you have installed the Gerbil hardware and are ready for your first project. The first project is cutting a circle out of acrylic or plywood. The second project is to engrave a picture on wood. The best way to get results […]
It has been a while that I wrote a blog about my K40 but many things were in train to fulfil the Kickstarter for my K40 Controller called Gerbil (after the firmware ‘Grbl’). The news is that the K40 shields are assembled and delivered to my fulfilment partner Skyzer Technologies and the remaining Gerbil controllers […]
Hi Backers, Having now received your pledges from Kickstarter, we’re all stations go ! We’ve already placed orders with the various suppliers for Gerbil components, and some of the first pro-pack reward components have already express shipped to our fulfillment centre at Skyzer Technologies Australia. Planning is underway with Skyzer to integrate, test and ship the rewards […]
110% Funded The Kickstarter campaign has ended and our project stands at $22,075 pledged, 110% funded from 168 backers. Wow, what a success! Now, it’s time to get busy for me (aka the creator) and my friend Dan. 14 Day review window from Kickstarter There is a 14 day review window from Kickstarter for reviewing, […]
The Makerfaire is over and now the time has come to get the Gerbil Kickstarter up and running by end of June. Two components of the Kickstarter that we need to solve are the intro video and the second is to re-evaluate the production costs to ensure we can deliver this for the price on […]
Today I’m writing about how to calibrate the drop in controller so you get the best engraving from the K40 laser. While I was at the Makerfaire in San Mateo, I realised during the conversion of Nick’s K40 machine that I never wrote instructions on how to get the best engraving. Nick was so friendly to lend […]
PPA calibration refers to discovering and setting tuning factors for electromagnet timing. It is performed to: While the default calibration figures usually work well, in some cases, the default tuning factors need to be changed to get reliable rotation on your PPA, and/or Achieving highest possible speed operation of the PPA Finding the best tuning […]
You’ve turned on your Personal Particle Accelerator, but aren’t getting the results you want ? First, try the basic checklist: Completed the construction, Read the safety advice Performed the commissioning tests Attempted starting the PPA ok, here’s the next level of detail: The ball rolls to a stop, apparently unaffected by the electromagnets: Confirm the second-from-the-end LED […]
