Happy birthday :) from Cologne!

USB data cable ???

Read it as: "A 74LV1T125 buffer is connected to pin 17, with the higher output voltage (5v) as on any other pin (3.3v)."

http://www.pjrc.com/teensy/teensyLC.html Teensy-LC provides a 5V output to directly drive WS2812/NeoPixel LEDs. A 74LV1T125 buffer is connected to pin 17, with the increased output voltage available on another pin. You used PIN 17?

Did you see this pin assignment: https://forum.pjrc.com/threads/26015-3D-Printer-Software-with-Teensy-3-1?p=51231&viewfull=1#post51231 ?

Is it so terrible difficult to ask for help in this forum?

Mostly compatible teensy-family plus new prozessor family/typ plus boardversion: 3.64.0 3.66.0 (No version 3.6 or higher ever)

May be mid of the year...

The code writes every loop current data to SD. displayInfo() starts only when new data arrived. With Brackets SD and displayInfo() are in the same block.

Your code needs some brackets.... The delay in displayInfo(); should better placed in loop(). //MAIN LOOP void loop() { // This sketch displays information every time a new sentence is correctly encoded. while (gpsSerial.available() > 0) //enabling the GPS Module if...

Look at the Phoenix-Project with PPM addition of CopterFail: https://github.com/CopterFail/Phoenix-FlightController/blob/master/libraries/P_Receiver/Receiver_teensy3_HW_PPM.h

MacBookAir6,2,ARDUINO 1.0.6, TEENSYDUINO 1.24, update to El Capitan Can confirm this behavior for both example scripts.

Yes, i did so...

Ups! Don´t know... Do you have hardware with teensy 3.x?

Yes, forgot it! :mad: I tried all board and stepper-driver combinations and found that DRV8825 makes the difference: Key differences between the DRV8825 and A4988: The timing requirements for minimum pulse durations on the STEP pin are different for the two drivers. With the DRV8825, the high...

i finished testing hardware of stepperdriver-module with breadboard and my contollerboard. Now the controller is connected with the endstop and (first) the x-axis motor of my felix-printer. My problem: the motor doesn´t move with marlin, but moves fine with an AccelStepper based test...

Congratulation! After getting a new power supply i decided to take the "modular" approach: a great controler-board holding a teensy 31 on beakoutboard, two stepperdriverboards (2x3max DRV8825), one PWM-board. Today i will test the first stepper. My plan is to solder and test 3 stepperdriver and...

No Direction;-) Teensy 3.1 inputs are 5V compatible. Only "DOUT5V" pins need level shifting.

I am stuck, because the ATX power supply doesn´t work. :-( I did a first pin assignment ... on paper. Because i need two HCT245 and there is little space on the board, i may change some pins. This is my current(!!!) definition for board 85 in pins.h...

Little progress Little progress with my Teensy 3.1 to Ramps 1.4 adaptor using: - Teensy 3.1 - Tall Dog LLC Teensy 3.1 Breakout - Arduino Mega Protoboard with stackable headers - Ramps 1.4 - ATX power supply/Felix frame

"Print Panel" is now "Manual Control" and they removed the "Fake OK" Button... There is no development of the mac-version! |-(

Not Ramps... Repetier-Host -> Print Panel -> Fake OK I will look into this on the weekend! I should decide to build a complete controllerboard or adaptorboard Teensy 31 to Ramps 1.4!? An adaptorboard seems more simple!

Thank you, Paul, for the product and the great support! I could compile and load, using a little board with two stepperdrivers (for "polargraph" or "self balancing robot" "missions"). Readapted pins.h and baudrate in configuration.h to 115000. Using repetier-host i could send move commands to...

I tried to compile marlin some weeks ago. i am very interested, but i´m far away to solve the problems.

exp-tech.de cheaper and fast, paypal, max two days or oshpark two weeks ( don´t like the green design ;-) )

How to use on Teensy? Any explanation, example, tutorial?

Take a magnifying glass and inspect carefully especially the pins beside the processor pads.

Sorry, I forgot to mention this bug, found and solved it in a similar way last night.

Same problem with Ciseco "I/O POD microSD Card" from exp-tech.de. After formatting with the "SdFormatter.ino" example sketch of SDfat everything worked fine. Card: 4 GB SDHC (EXP-T04-024) As i see this moment, exp-tech.de has now audio and OctoWS2811 Adapter in stock, i requested three weeks ago!

You need about 60 x 3 x 20mA. May be the power supply isn´t strong enough. Its a good idea to test the logic with a single WS2812B or a NeoPixel Stick.

Two kits are on the way... Edit: Got them! Nice... :-)

Does Kit & Assembled include the surface-mount header visible on second picture? Thanks!

Power Input > 12V (Batteries, Stepper,...) Power Regulator Output 5V > 2A (first stepps with Leds,...)
