If I set my CnC to 12800 steps it wouldn’t be able to cut quickly and any movement would make it skip steps. I do not have enough room around the fibre laser to rebuild the rotary setup to a belt.Īnd yes you are right the more steps less accuracy less torque. I have other rotary’s set up for diode/co2/CnC the steps distance to move are calculated in a totally different way, same with the fdm printer as well. If I am understanding you correctly, to determine your line width you take the circumference and divide by steps, so 223.06 / 12800 = 0.0174265625 so line width would then be 0.0175 then multiples of this for split size? 0.035 or 0.070? Thank you for a very detailed break down of what you do, Use as large a step as possible without skewing or degrading artwork. Same as individual filling, the galvo moves so much faster then the rotary, and with a tiny step the rotary never comes up to speed increasing time even more. I try to limit my steps to avoid maxing it’s memory by using larger slicing, get really good results 500-3000 slices. Results will start to skew when using it on larger objects and if the larger objects are close together perpendicular to the rotary axis, margins will get smaller to the point the objects will overlap.Īgree with the galvo’s BJJCZ (EZCad 2) board handles the rotary a lot differently then the other machine types controllers. Where individual filling can possibly speed things up with a galvo/ rotary is when you are using the “Run Whole Shapes, If Possible” setting when you have lots of small objects like text. Better to keep steps on the dip switches 5000-6400 and use mechanical means to increase steps (Belt drive reduction, zero backlash gear drive reduction) Just my opinion, probably get a cussing for that from someone around here.ĥth, filling shapes individually will slow you down compared to filling all shapes in each slice, as the fiber galvo laser jumps hundreds times faster then the rotary spins. I have good results with zero overlap.Ĥth, more steps on the microstep driver = smoother rotation but less accuracy. The more accurately the measurement the less the need for any overlap. Then use divisor of split for line increment. That will cause a cadence that shows up in the annealing. Multiples of this number make a good slice, as there is no reason to tell the rotary to stop somewhere it physically can’t. This will give you the actual surface distance the tumbler will move with 1 step of the rotary. Third, for step/ slice/ LI, divide the circumference by the rotary steps. Second, you can increase the line increment to 0.01-0.025 depending on lens/ focus and formula below. The 300x300 is the ticket but you can get good results out of the smaller ones just setup is less forgiving. Its a little like the cleaning pass when doing 2.5d, why is it not a full clean, we don’t need whats being cut next to be clean we need the whole coin cleaned to stop the post processing or at least minimise it when the job is done.īelow applies mostly to my experience with fiber laser/ chuck rotary, Yeti and similar tumblers, working with both a 6400 step set up direct drive chuck type and a 34800 step belt drive chuck type.įirst, Stainless steel anneals black nicely with a large lens slightly out of focus. If your work is centred and and rotary centred as far as the machinery is concerned its a flat working area so why the limitation and split sizes? If anyone can explain why this coded for galvo rotary I could stop moaning about it and get on with the limitations at hand. The way you have to set up the stepper is so wrong 12800 rotations for 360 turn? Again is this a limitation of ezcad boards or what? No direct answers from digging in the forums. My personal belief how they have set rotary to work with Galvo is flawed.įirst you can’t get continuous rotary motion, you can with a diode laser running a cheap board, co2 so I don’t know if its a limitation with the ezcad board or what. If you have any large areas to do it becomes a nightmare especially if you don’t use fill shapes individually. This gives you the quickest rotary operation with Galvo and do do a full jacket around a bottle is 10 to 15 minutes depending on the design. set split size to 2x or 3x your line width. I have got my galvo working ok with rotary with the following process, 1.

Hey G’day, I have spent several days on this, I sent in a ticket several days ago to support still no reply.

Sure cuts a lot 2 split
