ferkles?
Don't need heated bed to do PLA????
Marlin firmware ?
TTL
low < 0.8 volt
High 5 volt
Everything about TTL and laser control
Have you looked at
i looked on eleksmaker for about an hour, very pritty....hmmmm

some pics and the board a mega/ramps 1.4, and not rigged up yet, having ferkles printing parts due to a failing heater bed at the mo, all go innit.(googling for a 240v pad..)
note on the driver board theres a third TTL pin on the power lead (jack plug lead), so +12v,-12v and a TTL. two other pins for the TTL posative and negative.

Munchit1,
Sorry for the late response. As to the simplify 3d thing, I highly prefer LaserWeb or just about ANY software that is actually made for lasers. It is much more customizeable and has many options. It's just a matter of generating Gcode.
I understand the PWM SXXX commands (XXX symbolizes your laser intensity). The issue is with all the drivers I use, the laser appears to ju

And I am not seeing a third marked pin on mine. There is one port for analogue, CN3, but that's not what we want.
just rechecked and yours isn't the same as mine after all.. ahh well, wishful thinking on my behalf.

hmm a penny dropped..
the extruder 'control' can be set from 0-255 in marlin, so its a pwm current to the extruder pin, pulsing the primary part of the laser driver board circuit, followed by the TTL pulsing...may cause problems, may not, hey ho...
maybe set the extruder pins to analog? i dunno.(analog as in constant DC...no doubts the power supply to the laser board is pwm of some sort or anot

... I'm using a small Arduino (Arduino Pro Mini clone) as an "intelligent" controller in my laser modules or as driver-interface.
The input signals are e.g. the STEP pulses, meant for the extruder stepper and an analogue voltage 0V-5V, regulated either by the CNC-controller (e.g. 12Bit-DAC of the ArduinoDue, "up-shifted" from 0-3,3V to 0-5V) or set with a trimpot ... and a "laserON" sig

... hmmm ... it's as simple, as feeding the pin for the extruder STEP to the TTL-input pin of the laser driver ... eventually you have to add a "level changer" (e.g. a TTL line driver or transistor circuit), if the TTL input of the lser driver won't run with the 3,3V from an ArduinoDue ...
how do you change the pwm to change the laser power? (assuming it's still running as a 3D printer

can i ask which TTl pin you attached to D9? I've got the same laser/driver, there's two listed on the board as TTL, one with 2 pins and one with three?
and a side note, is there a practical way to power the module from the extruder heater pin, (and the TTL to another pin?) so that it only turns on when the 'exstrude' is activated, the TTL controlling the power level.(assuming the TTL actually wo

the exsiting documentation is ok for exsperienced users...
the request was for a much simpler quick guide beginners can just read through in one go..
and apology excepted..
i got my hopes up with the board..so maybe some of my fault is there.

dood, i stated not specificaly at you
i also stated the web site is far better than any others
i also stated i metaforised and exsplaines why over and over
the whole point was why cant there be a concise simplistic manual....like an idiots guide.
reason.. a lot of folks are not up to reading all of those pages and cross referencing.....
regaurding your not understanding what i said?..........

how about just adding a 'begginers' set of instructions?
with quite literal exsplansions,
e.g.
this pin coralates to polulu pin ''whatever''
when enabled with this command ''pin hi'' placed into 'this section' with or without * or dash etc.
actual instructions dummified....with the actual answer and where to put it? the rest is purely an intresting to read.
reason why.....the majoruty of us

posative feedback, tecnicaly is NOT feedback that is posative! posative feed back in its simplest form is actualy getting 'accurate' feed back.
negative feed back is literally getting no feed back of inacurate feedback.
then we get to misconstrude 'accurate'... because after all the witty intelectual battle is far more important than anything factual....a bit like old women in the battle of the

hi all, it's your old munchit1 here..with a methodic 'reply' regaurding 'support' in general.
doesnt matter how complaints about the lack of support is worded it boils down to....
arther?not specificaly 'targeting you here' but..a sinario...
you are obviously inteligent, more than a big most, as such it's safe to assume you suffer serious frustration at having to answer 'half baked' questions

Hi all,
I spend last weeks a lot of time. And now most parts works.
Marlin4Due works with RADDS (also the RADDS-Display with the Back-Button) and also should work with RAMPS-FD V1/V2 (but not tested!).
All the extras which are new in the main-fork are implemented in Marlin4Due.

Firmware - experimental, borrowed, and future
problem solveved..bricket it without touching fuses..blah blah. chip ID differs and cannot comunicate, please read for 72 hours to find out it's bricked lol...eeerghhh.
why do the chip people and the board manufactuers not like you using the stuff? it's not like you'll buy another one is it?

basicaly it shows how many steps its moved as aposed to how many millimeters.

hi all.. i remember reading thread that said you call the amount of steps travelled with a G code comand that displays it, does any one know what it is?

I have no idea what you are on about?
Are you on about faults in cad files causing unprintable objects? eg, the rubbish that is sketchup? Personally I've had no problems printing direct from decent CAD programs like Fusion360. I also have very few problems with sketchup, but you need to know why files become non-manifold and keep within the restraints of sketchup. Basicly, don't g
