Any G-Code Streamers work with Marlin? - 9 years ago

I am running a Ramps 1.4 with an updated alter of Laser Marlin. I will need a G-Code Streaming program for the full gray scale images. All of the streamers are made for GRBL. Are there any of the streamers that will work with Marlins? Why is everything made for GRBL when GRBL is soooo limited? I am trying to avoid having to use GRBL on my Ramps board if at all possible.

Re: PCB designs for laser power regulation? - 9 years ago

You don't need a power regulator. Just use a Flexmod P3 Driver. It is only $35. It takes a constant power supply and uses a trigger. You should always power your laser with a seperate power supply from the one you are using with the ramps or anyother board espically if you are using stepper motors. The back EMF from steppers is where you would get a voltage spike from. I used (2) 12v / 5A power s

Re: choosing 2W laser diode + driver - 9 years ago

Dtr's laser shop for your laser. You want an M140 laser diode and not the A140. He is a very big deal on the laserpointer forums. You want a flexmod P3 driver. You can get them at innolasers.com but always email to see if they are actually in stock. They sell out and don't get them back in stock for months. If they are out Dtr may one.

Re: Several Questions - 9 years ago

I am screwed if your program doesn't do it automattically. I thought it could. Looks like I have to figure something else out. Sigh.... I hate GRBL, I wish someone would fix it so it was usefull.

Re: Several Questions - 9 years ago

I tried using the ASCII protocol and it didn't work. It was strange when I would connect with that protocol the display would turn off and on every 5 seconds or so but I had no control. I could go to manual contol and issue a move command and RepHost would process it (not stay in the buffer) , but nothing would happen. I don't quite know why they aren't talking. It could be from some of the laser

Several Questions - 9 years ago

I had several questions on how to configure Repetier firmware and where to plug in the trigger on the ramps 1.4 board for laser engraving and triggering the laser. As well as Repetier Host working with Marlins firmware. I am not sure what configuration settings I need so RepHost firmware will trigger my laser on my Ramps 1.4. I thought I saw something about using the fan output. If it is the fan

Re: Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

Repetier, removing the extruders from the temp. tab in the setup is what fixed it. I thought since I was duplicating the output to E0 that I had to have extruder 0 in the temp tab in it or it wouldn't function. That was wrong thinking on my part. Here is the config file so if someone else has an issue they can use it. Thanks for your help.

"I wonder how you intend to engrave without modulating the laser." It will be modulated by a dac circuit.

Re: Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

Ok I tried the new firmware. There was no change. I moved the output to E0 and there was no change. So doesn't that mean it is in the firmware?

Re: Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

I will make a new file off the new patch today and double check the pins. If I get the same thing, I will change the output from E1 to E0 to verify there is nothing wrong with the ramps board. What is the best way to disable all of the heat and extruder settings? Like min and max temps, preheat, ect. I was putting in 0 for everything but ran into issues. I ran into compling issues with extruder

Re: Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

I thought the same thing already. I have interchanged all motors, and drivers. The main thing is that did run correctly in marlin but I have not tried again since I tried repetier. So it is possible something went wrong. I will try switching from E1 to E0 and see if that fixes the issue and I will reload marlin if that doesn't work. I had marlin working fine with the discount SS controller. I c

Re: Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

I have tried both versions of the firmware. I have figured out what is happening. Once I took the belts off of my Y drives I could see more what is happening. The second Y motor being output to E1 will only spin in the same direction. So if you tell it to move in the + direction it spins counter clockwise and if you tell it to move in the - direction it still only moves in a counter clockwise mot

Re: Marlin configuration issue..No axis moving in negative direction.. - 10 years ago

There is a setting for allowing negative travel. It is in the configuration.h file.

Re: Help with Marlin Laser Alter - 10 years ago

I did get the dual Y working fine via my reprap discount controller but I couldn't get marlin to talk to any kind of software like pronterface or repetier. Sorry I didn't reply I didn't get notification.

Repetier Ramps 1.4 Dual Y Stepper Problem - 10 years ago

I am building a cnc style (cartisian) laser engraver. You can see an old pic of it here I am using dual Y steppers. The main issue I am having is I can move the Y axis in the - direction fine but when I try to move in the + direction one of the steppers doesn't want to move or is moving wrong. The axis goes a little crooked but it will move, so the the second motor is not locked but is not moving

Re: Help with Marlin Laser Alter - 10 years ago

I figured out the E1 output duplication issue. I had E0 on two of the fields. Also figured out that you don't have to add INVERT to code so the E1 will run in the correct direction. Just have to plug motor in backwards. Thanks for the help........

Re: Help with Marlin Laser Alter - 10 years ago

Ok I really need help. There is something wrong with my code. I am not getting anything on E1.

Anyone?? I just need someone to look through my code and make sure I got everything. I am a noob and marlins is pretty complicated place to start.

I am going through the same issue. If you look at my post there is a link to a shapeko post. You can also look at the files I posted. I am not done yet but mostly there.

Help with Marlin Laser Alter - 10 years ago

Hey all, I needed some help to make sure I got the coding right on my altered marlin. I am making a 2 watt laser engraver (cnc style). I started a project on openbuilds (Link). I plan on doing full 8-bit laser engraving with pic engrave. Pic engrave uses the output from the Z axis runs it through a DAC to change the signal to analog then to the laser driver to change the intensity of the laser.
