Trouble Shooting / crazy new laser and crazy me
« on: February 25, 2020, 12:24:53 PM »
Hello guys
I was trying the new TTL laser and the first 2 days I was able to make beautiful images on non-stained wood while on stained wood it had a golden effect.
on the third day I tried for 2 hours to cut 3mm of birch, without success.
after this (the images circled in blue) the laser was no longer able to burn on unstained wood while it became capable of burning stained wood.

General Discussion / laser module button use?
« on: February 09, 2020, 11:19:37 AM »
hi guys,
i bought a ttl laser module and mana se board.
on the laser there is a button that I thought operated the low power.
if I press it on the laser board the green LED lights up and I have no laser emission.
if I press it again on the laser board, blue LED lights up and I have laser emission.
it's normal?

ttl is fantastic, you can see the change of beam power changing little on the values (30 and 35 are different!)
also 2.5w ttl seems to me more powerful than 3w no ttl

EleksMaker Mana SE / offline sd controller

Hello guys,
i bought a mana se board with auxiliary socket

mane se

do you know if this controller works to burn without a computer (only from sd)?



Trouble Shooting / acceleration? dinamic mode?
« on: May 09, 2019, 01:11:07 PM »
I'm trying to do an excellent grayscale.
unfortunately when the laser reverses it leaves more burn.
to get rid of the problem I have to raise acceleration to 3500, but the laser vibrates and leaves a salmon skin effect.
I put acceleration to 2000 trying with the dynamic mode I eliminate the problem but it gets worse scales and the clear part gets thinner.
moreover in the last tests then 100% is lighter than 80% bronze instead of black.
what accelerations do you use? dinamic mode or not?

Trouble Shooting / lost step?
« on: May 07, 2019, 12:59:09 PM »
i have a strange problem:
I burned the samurai (700x950 0.2res) and it came perfect.
I resampled at 1400x1900 and burned at 0.1res and missed steps.
I burned other things, perfect.
I still burned the samurai (too dark but that's not the problem) and missed the steps again.
every time the line is skipped all the drawing moves to the right.
I didn't stop the work, it stopped by itself, with  laser on.
other prints later are good.
why does this image cause me problems?

here the image:

T2 Engraving / memory zero position?
« on: May 03, 2019, 12:15:21 PM »
Hi everyone,
I have a question on T2:
1 I set homing
2 sets the piece zero
3 start work
4 push the envelope to pause the work and decide that it is not good (x50 y50 coordinates for example)
5 push X and return to the main window to apply changes to the image
- I generate gcode again

and in laser controller the coordinates are now x0 y0 (machine and piece)
Am I doing something wrong or do I need to remember always to reposition lasers in 0.0 before step 5?
it would be nice to go back to the controller and find the coordinates where they were

General Discussion / my updated laser
« on: March 29, 2019, 12:45:16 PM »
Hi guys,
still there is some thread to fix well, make a bed and fix usb relay and aie extractor; but they are minor details.
roughtly I can be satisfied :)
I made wire covers in the frame grooves, energy chains, for the x axis I used a flexible meter, belt tensioner, a connection board for arduino, an electronics cover and the air assist.
I hope you like it
i can't upload the photos...

Trouble Shooting / help laser upgrade
« on: March 08, 2019, 10:16:43 AM »
Hi guys,
I'm upgrading my laser and I have two questions:
-I bought these limit switches

  and would like to know if I can connect them NC (I have doubts as they have electronics on board)
-I mounted this fan

, where can I take power? with separate power supply, connected to the laser fan or on the board (I have no free connectors)

General Discussion / I'm here too
« on: February 17, 2019, 08:16:08 AM »
Hi guys,
I've had a laser for a couple of months and there are a lot of upgrades to do, so today I have a 3D printer too. alfawise u30.
I made 2 prints and they came well, I'm very happy.

Trouble Shooting / crazy laser
« on: February 13, 2019, 12:54:51 PM »
today I did raster in vector mode plus filling.
when the work is finished the laser (turned on) went into the lower left corner and did not stop.
I found the values x -20000 y-800 and the pulley slipping on the belt.
I reset and made quick tests. all normal. I use lasergbrl, it had never happened before.
next step mount the endstops

General Discussion / laser stove :)
« on: February 04, 2019, 12:13:24 PM »
Hi guys,
I read a lot of threads and I became paranoid: my laser was resting on a chipboard and needed continuous surveillance.
Now I have created this "monster" and I can leave the laser to work alone.
In the worst case the garage is heated.
It's not very nice but I make it with scraps. I have a lot of scraps...
I hope you like it.

General Discussion / new newbie
« on: January 08, 2019, 11:39:08 AM »
 hi guys,
I'm Simone from Italy and I recently got a laser engraver 50x 56 3W
and now I'm studying on your beautiful forum. I did several tests, many failures ... good results with the b / w discrete with dithering and bad with the gray scale.
I loaded gbrl 1.1f and use lasergbrl, I also tried t2laser trial but it is still too complicated for my skills.
