3018 CNC SOFTWARE
In addition, the Vectric & Carveco software is what we mainly use at Ooznest, so therefore we can provide the best support possible. We have a guide on running your first project on the WorkBee - First Project From our experience, these are the easiest programs to use but are still very powerful.īoth programs have beginner tutorials projects to get you started: Either Vectric Cut2D, VCarve or Carveco Maker. If you are a beginner we would recommend buying the software we offer with the machine. If you haven't got much experience with a computer and have not really used design programs before then it will be a learning curve, but a good one! If you have used any type of computer design programs before, then learning the programs that operate a CNC Machine should be fairly easy. The 3018's usually don't have homing switches, which means that the zero point of the machine is random, in fact, wherever you have the head when you power the machine will be zero.If you are an absolute beginner to CNC Machining, the learning curve really depends on how competent you are with a computer. In LightBurn, you'll also need to enable Overscanning when using either Fill or Image modes in LightBurn, and may need to increase the amount quite a bit above the default if your machine has low acceleration. More information about configuring GRBL can be found here. If your engraving or cutting doesn't seem to be getting the power you want, try going slower, or at least check that you are not asking the controller to go faster than it can. If it ran at half the speed, but left my power at 100%, I'd get a much darker burn than I expected, so the controller cuts the power in half to match the loss of speed. If I asked for a line at 100% power, at 50mm/sec, but the controller can only go 25mm/sec, that's half the speed I asked for. With GRBL, in variable power mode, if you ask the controller to go faster than it's allowed to, it will reduce the output power to compensate. In mm/min those are 2250 mm/min and 1125 mm/min. Unfortunately most 3018's also have their motor stepping rates set very high (either 800 or 1600 steps/mm), and an 8 bit GRBL controller will only output about 30,000 steps per second, so you're limited to a max of 37.5mm/sec (if you have 800 steps/mm) or 18.75mm/sec (if you have 1600 steps/mm). This will likely be set to about 500, which means 500 mm/minute, or about 8.3 mm/sec, and this is really slow for a laser. Maximum speed for the X and Y axis are controlled by $110 and $111. This is required for LightBurn to correctly understand the machine. Status reporting is controlled by $10 - Set this to 0 which will tell the machine to report workspace position, not absolute machine position. Variable power requires that the M4 tool command is used instead of M3, so make sure you are using the GRBL and not GRBL-M3 device profile to take advantage of variable power. Using this mode means also allows for Variable Power mode which means the laser adjusts the power output from 0% at a dead stop to whatever power you request when it gets to the requested speed. Laser Mode means that you don't have a rotating spindle tool, and therefore we're not pausing to wait for it to speed up / slow down when the PWM output changes, and the PWM output needs to be turned off when moving between cuts. Set this to 1 (or true / enabled in Machine Settings). More information about configuring GRBL can be on the official GRBL documentaion site. The settings you'll most likely need to change are listed below. Both are showing the same values, but the Machine Settings view in LightBurn is a little easier to use.
To see the existing settings, you can type $$ into the console in LightBurn and press enter, or go to Edit > Machine Settings. You're trying to move too fast, which is why you don't get enough powerģ018's are pre-configured for use as CNC machines, not lasers, so their settings and speeds will likely need to be changed to give you acceptable results with LightBurn.Turn on Laser Mode to get rid of the travel lines.
