i just tried ;-) and as far as i know higher pwm is not possible. which hardware do you use? from my experience problem appears mostly on brushless fans, depending on their internal electronics. they cannot handle pwm on small pulsewidth. And as re…
-
btw, the fans i have dont even start at 50% pulse width and 900 Hz PWM frequency. so adding the cap is nothing else than building a kind of step down converter.
-
simplest way is to add capacitor parallel to fan. around 2 to 10 microFarads should be ok. take care on polarity! had same problem with some small fans.

for shure you can modify refer for example thread " laser section" for some informations.for modification best solution is to use custom Events as it makes future updates easy
-
No, you just can switch ON and OFF. Values >199 switch Laser on Values
-
whats the value for this : #define ENDSTOP_Z_BACK_ON_HOME
-
Ok, thank you for the hint , so i can use the Display now on pins70/71 , keeping my other I2C peripherals on 20/21. may be i´ll play around with that and if i find a solution to have eeprom and Display on one Port I´ll inform you
-
so try to reduce Max_Jerk from 20 to 5 , if that helps you can increase it in small steps Keep max_ZJerk as it is
-
so you also changed ui.cpp line 947 from u8g_InitI2C(&u8g,&u8g_dev_ssd1306_128x64_i2c,U8G_I2C_OPT_NONE); to u8g_InitI2C(&u8g,&u8g_dev_ssd1306_128x64_i2c,U8G_I2C_OPT_DEV_1); ? when keeping device0(pins 20/21) there seems to be …
-
thanks for info, i´ll check if it works on my setup
-
what is your jerk setting ?
-
i saw "featureKeys": "0", in your config , you should set it to 1
-
ok, so i cannot use for my purpose, Thanks for answering
-
seems to get a lot of typing :-)so i´ll give it a try
-
Ok, so I´ll have to find a compromise between Speed and precision.or/and Change the optocouplers as there are really fast ones available
-
I already use Due so i think my stepper drivers are too slow as i need stepper high delay and direction delay 2us . seems the built in optocouplers are too slow
-
is there a trick to go with higher steps/mm?
-
there is a simple way to prevent beds with a big mass from overshoot. put temperature sensor close to heating element. (my heatbed is 400*200 mm , 12 mm thick) i use pwm for temperature control and it works like a charm.

MartinH said: In arduino tools menu select board type Arduino/Genuino Mega or Mega 2560processor type ATMEGA1284 Arduino Mega is equipped with ATMEGA2560 or ATMEGA1280 not 1284
-
ok, so then it´s the 1284p but i´m not shure if that is compatible to the sanguino. as far as i know it´s not supported "out of the box" by arduino ide and there are a couple of arduino "add-ons" out in the net so i ´m sorry i cannot help. so may …
-
ok that´s problem of syncronisation , as i´m not familiar with this board so take a look at it which controller is on that board and also which usb-controller
-
you have the wrong board selected in arduino ide. goto tools/board and select the correct board. i don´t know which one is compatible to the anet but ithink it might be arduino/genuino mega
-
ok, will the next update also contain the display change for laser/cnc mode?
-
checked code again, cartesian version is not correct. in motion.cpp line 2752 (warmup condition) we need the 255 :-)
-
i did the changelog check , so it was just the wrong line .had to check it because my due setup (there i changed manually)was ok so i wondered what happenend.anyway it´s fixed now
-
can you please give me a hint what to change to get the secondspeed work on 16 bit? just want to see if i get some visible changes as soon as i receive my 5 Watt Laser ok,got it , missed the public uint8 secondspeeed , first just saw the one in que…
-
ok, so bug happened with changes for warmup :-)
-
ok , thanks. @Repetier : there is another guy also with a delta fighting with this issue see Post : "Laser turned on on all moves".i loaded configuration from this guy to dev version and checked on Mega/Ramps.so it does not switch off laser during…

already merged avr version vs due version. no difference
