  • keep rest of the code in , just set in configuration.h  LASER_PWM_MAX 4095 and in Customevents.h #define FEATURE_I2C_MACROS false #define FEATURE_EXT_PWM false #defin…
  • only one is necessary. i personally prefer the analogcontrol.
  • cannot say something about that.may be you can post a datasheet of your laser.
  • that will not work, you need a little delay after ignition in order to melt the material before adding more with your extruder(wire feeder). think it might work adding something like laser warmup function and as repetier said use fake thermistor and…
  • it´s not a stupid, it´s a working solution. may be you need more background , it´s explained multiple times here in forum. using the pwm pins is based on timers and timers are occupied by other functions so that is the reason for the low pwm frequen…
  • so i guess you want to do something like engraving photos... i spent the last two months with that stuff.the only thing i can say about that : use an external PWM controller like i do and it´s exactly written in the custom events.
  • what kind  of laser do you use? there are so many different laserdrivers out there , some just use a enable pin and are sold as pwm"able" which is nonsens, of coarse they work somehow  , but not as they should. the ones i have are limited  to 1kHz o…

  • see: http://forum.repetier.com/discussion/comment/11201/#Comment_11201
  • so on the adafruit board level shifting is done, no problem. take care, 3v pin on this board is OUTPUT. don´t use it. aux 3 is occupied by sd-card... mosi,miso and clk can be used multiple(on avr), cs not so just don´t plug in the sd, use pin53 for…
  • so i guess you use nema23 motors, hopefully driven with more than 24 Volts... i also use them in my experimental machine. i also guess you have the ones with the dipswitch current setting... so from these i have two versions... from outside they lo…
  • how did you hook up the two motors? 2 drivers? or 1 driver, motors parallel? or 1 driver, motors in series?
  • ok, so i understand, the portal is not closed on the bottom and you place the router on top of material. but anyway , don´t you have a closed frame ?
  • ok, i saw different types of the breakout board , some with the level shifting , some without, but both sold as 3-5V :-( so may be you can send a link with picture of the board. configuration  in Configuration.h search for:  #define SUPPORT_MAX3…
  • Think you fried the devices.... refer MAX31855 Datasheet : https://cdn-shop.adafruit.com/datasheets/MAX31855.pdf They are not useable on 5V Systems ....
  • As I´m just wondering about the necessarity of two motors on one axis. can somebody explain why please? so for me in a cartesian machine the only two reliable ways to drive two rods on one axis is -a) one motor, rods coupled via timing belt -b) if…
  • If that´s the case use a resistor to pulldown or pullup (depends on your laser driver)the pin that controls your Laser during initializing. Value of 10 KOhms usually works. This is just necessary as the Pin doesn´t "know" of being input or output an…
  • referring Picture you connected heatbed to Extruder heater Pins.you also did not connect power for heatbed. refer this: http://docs.my-home-fab.de/images/my-home-fab/artikel/hardware/electronics/reprap-ramps/ramps-1.4-schema-1920px.jpg
  • I´ll check it on my VFC´s, i have 2 of them. but that´s only one part. Spindles also are different so that´s why i think we need  a place in config.h where we can define a factor for calculation pwm to rpm.

  • should be possible with adding another placeholder , same principle as i did with the work coords. will take a look at that and make a suggestion , may take a few days so i´m busy on other things. to show spindle speed we would have to implement pw…

  • thanks, so it´s just the way i do actually. did some basic programming in turbo pascal  and assembler during my technician education beginning of 1990´s . unfortunately i did not continue until 2014 , that´s where i started with the arduino stuff be…
  • OK, thanks for your help, can you recommend some literature to improve my programming knowledge as there are so many things i don´t know about...?
  • OK, but seems there is some mismatch in UI_STATUS. if i use the non F version it doesn´t compile... see DisplayList.h  : #define UI_STATUS(status) uid.setStatusP(PSTR(status)); #define UI_STATUS_F(status) uid.setStatusP(status); are the defines …
  • OK,Thankscompiles now with using : UI_STATUS_F(buf);andCom::printF(buf);
  • forgot one error message :error: array must be initialized with a brace-enclosed initializer ist pointing to :    Com::printFLN(PSTR(buf));
  • believe me  it´s better to have the noise than having Filament blocking the hotend  ;-)i´m a little experienced in these e3d clones , don´t try to run it without the fan
  • if it is Setup shown on Picture from the link, the fan is used to cool hotend .This has nothing to do with a fan blowing to cool the print as you mention.it is needed for this type of hotend to prevent Filament from sticking in the heatbreak. so doe…
  • so some more strange stuff :i use that code on DUE for unhandled MCodes , works finebut on AVR it doesn´t compile it just Returns :exit status 1 initializer fails to determine size of '__c' CODE:bool Custom_MCode(GCode *com) {     char buf[20];   c…
