Re: Project: Teacup Firmware - 9 years ago
QuoteTraumflug For just X and Y you currently have to define Z and E as well ... and ignore the latter two. Patches to change this are welcome, of course, some 50% of this work has been done already. Power is like a heater without temperature sensor. Using M106 to regulate between S0 and S255. Simply remove the other heater and both temp sensors from the template. The same could be used for theby ghost2501 - Firmware - experimental, borrowed, and future
Re: Chinese CO2 cutter and Marlin - 9 years ago
You definatley want to have one 5v signal that is on or off for turning the laser on or off. Usually the chinese power supplies have a 0-5v analog input for power. If you use pwm at high frequencies the analog input thinks its an analog signal and turns it into a 0-5v depending on duty cycle. There is no real reasong to pwm the laser on adn off in pulse mode. That would be more for RF lasers andby ghost2501 - Laser Cutter Working Group
Re: Project: Teacup Firmware - 9 years ago
I already found a inkscape plugin that spits out pretty nice g-code It lets me choose what commands for laser on and off and the power etc. all of the speeds you should check it out. Its default is m106 and 107 for on off with s commands for speed. If you could just have one pmw pin out for the speed command and one pin out for laser on and off that uses pwm that is all I should need. In the enby ghost2501 - Firmware - experimental, borrowed, and future
Re: Project: Teacup Firmware - 9 years ago
I found a version earlier but cant find a thread on i of teacup firmware made for laser cutters All I need is x and y movement adn endstops. plus apin for firing the laser and a pwm pin for power. If i had too I would use a seperate arduino to regulate power because all I cut is 1./8" acrtylic it would be the same anyway.by ghost2501 - Firmware - experimental, borrowed, and future
Teacup laser on a Yun - 9 years ago
I was wondering if there is anyone that has a simple xy laser setup wtih teacup and what solution do they use to fire the laser and set power. I have a Yun I want to try to use. Also any links to the laser part of teacup would be great. I dont need any temp monitoring or any other axis or hotends beds etc. so hopefully it can get gutted. I was hoping to run the Yun straight to a set of Geckodrivby ghost2501 - Controllers
