aligning the XY gantry with laser tube

are there any procedure's to align the XY gantry so that it aligned correctly with the laser tube? Do you have to pull the gantry out of the case to do this. I have tried to align the mirrors and the best I can do to get the dot in the center of the mirror is about a 3 mm space between the dots when...

Re: K40 Air Assist install questions - Lens direction

I was going to ask the same thing, I also have to 18mm air assist and purchased the 18mm lens and hope that I put it in correctly. my lens is flat on one side and curved outward on the other side. I installed it with the cure side facing upwards. Is this correct?

Re: Laser tube wont fire, could use some advise

well I tried all sorts of bed heights and speeds and power setts up to 60% and all I get it to do it etch and not cut all the way through. even with 3 passes it didn't cut through 1mm cardboard. I decide to check the mirror alignment and that might be the problem. I used tape over the carriage mirro...

Re: Laser tube wont fire, could use some advise

I feel like a fool, I just went back and checked everything a gain and I had the E-stop Button engaged, thats why it would not fire. Well It is firing now and here is the test. It was supposed to cut through the 1mm cardboard, but it only etched it. I now have to figure out the etching and cutting s...

Re: What Motor Driver can be used with DSP E5

Marco: what do I do with the +5V connection on the E5 then. I currently have the PUL going to the +5 PUL and the DIR going to the +5DIR and the +5V going to the +5ENA on the Micro Step Driver. So I can just leave off the +5v wire all together and only use 2 wires instead of 3?

Safety Glasses

Can anyone recommend the correct safety glasses to purchase to use with the K40 Laser. I need to order a pair, but I don't know what the wavelength of the laser is to buy the correct ones.

Thanks Dan Stuettgen

Re: K40 Laser PSU Pin Outs

we after a weeks worth of working for a couple hours each night I have the K40 upgraded with the E5 DSP controller and was able to figure out most of the wiring. The only thing I have not been able to figure out is what wire from the Laser PSU goes to the TTL connection on the E5 DSP controller. Wou...

The left connector , the black and red wires go to the power switch, one yellow goes to the analog meter , the other yellow goes to chassis ground. The tw...
