I have completed assembly on my DIY Mini CNC Woodpecker and initial tests ran fine. One thing, I do not see the drawing of the test item on the screen in GRBL. Is there something I am not setting correctly? The machine runs properly but I do not see the word iPhone or the blade to indicate where it is at in the run. What is the board supplied with the CNC? Also, is there a schematic for the board? Also a map of pin assignments? One of the pictures included with the files indicates there is connections likely for an LCD screen and the other pins may be for limit switches? The supplied 24V did not have a connector to plug into the board. From what I have read about drift issue with Z axis, is the motor simply powered directly and not through the board? I have also purchased the laser module which will arrive soon. I think this MUST be powered through the control board, I see a switch labeled LASER/MOTOR which I am sure needs to be set to LASER. Thank you, Tim
oppemaniac posted a topic in RS232/GPIO Shield for Raspberry PiHey guys, I try to use your Linker Kit IR Receiver with my Raspberry Pi Linker Baseboard (that with MCP3008, not the one from your wiki). Unfortunately, the PIN description on the board confuses me. While the one from the wiki has completely traceable descriptions (http://linksprite.com/wiki/index.php5?title=File:P24-1.jpg), mine has for example no D18! And some are double on the baseboard! The analogue channels, UART,I2C are correctly noted on the shield. But how to map the Digital GPIO to the raspberry ones??? Here are the Digital GPIO Pin descriptions from my shield (for each of D1-D12) from top row to down row: (D2,D3), (D4,D5), (D5,D6), (12,13), (13,14), (14,15), (D15,D16), (19,20), (20,21), (21,22), (25,26), (D26,D27) I want to use the IR Receiver at Raspberry GPIO 18 via the Linkerkit baseboard... Where is D18? Sincerely yours
is Spruce - STM32 Arduino Maple Compatible Board's schematic wrong? ENC28J60 and SPI flash use same SPI and CS pin, how is this possible? schematic is here ; http://www.cutedigi.com/pub/Arduino/Spruce/Spruce_schematics.pdf Board Link http://store.linksprite.com/spruce-stm32-arduino-maple-compatible-board-without-lcd/
