It turned out the problem was the white paper. Once i changed that for colored one all was good. The best results i got on red paper.

RE: Incomplete cuts?
Thank you very much Zax. I will try to get new power source and will report back.

RE: Incomplete cuts?
Laser: 2500mw ttl pwm
Supply: very same as the one what came with the frame.
“Ccd Star
model: EZ-1222 18B
input: 100-240
output: DC 12V 2.5A”The laser came with a cable for direct power supply connection, but when I use it then I can not connect the laser to the controller board. Laser is basically constantly on and I have no control over it.

RE: Incomplete cuts?
Hmm.
I have two power supplies. One came with the frame and one with the laser unit which i ordered separately. This described problem is happening on both supplies.
So now I am curious. Is there any way how can I connect the laser to separated power supply AND to the controller board at the same time? Is there such a cable which would allow me to create such a connection?
Or what reliable power supply replacement do people tend to use? -
RE: Incomplete cuts?
This is what is happening. I have enabled reduced acceleration and disabled dynamic laser. Didnt helped.
Those numbers are from the T2laser from help menu -> samples -> feed rate, power test etc.
On another pic you can see just brown line, not cut through and then the cut continue...honestly no idea what is going on.

RE: Incomplete cuts?
I have the very same problem. Not finished cuts if speed is highier than 400. More or less ok if speed is less than 400. But then fine details are burned. And another issue i have is that the laser burns through, then “half” burns (doesnt burns through, the cardstock just gets brown) and then keeps burning as it should. No idea what is going on. Software full version t2laser, grbl 1.1e.

How to connect these cables (2500 mw ttl/ pmw laser unit)
Hi,
I am a bit confused about the wiring. These 2 cables came with the laser unit. I can attach the longer one to the controller board and laser, but what am i supposed to do about the shorter red/black cable?
Do i actually need to connect that shorter cable? There is only one white socket on the laser. If i understand it right - the longer cable connects laser and the board (marked as a “laser” socket) and if i wanna power up the laser without the board i can use second one - shorter cable. Is this thought correct?
P.s. the red wire on that shorter cable has only one pin. What is this wire for? If its for fan how do you connect it?Thanks in advance.

RE: Firmware upload error
@Zax
Would this one work for me?
https://www.buyapi.ca/product/atmega328p-au-arduino-compatible-nano-v3-0-r3-board/They say its with bootloader and its soldered.

RE: Firmware upload error
@LogansRun basically i just have to swap mine broken one with the new nano(compatible) one? Nothing else?
No extra soldering etc? -

@Zax
zax please can you tell me if this is nano with genuine atmel or just cheap chinese knockoff?

i know i see the logo but you never know.i tried to change usb cable - didnt work
i tried to use arduino ide software - didnt work
i tried another computer - didnt work
i tried to use xloader - didnt workhonestly if this is genuine atmel i have no idea what is going on then. i just cant upload any grbl no matter what. btw when connected, that red light doesnt blink at all. it is fully on. is it good thing or bad?
in arduino ide i get this error
avrdude: stk500_disable() : protocol error, expect =0x14, resp = 0x95any idea?
thanks in advance!
rob!what way can i reset nano please?
