Do I need to tie the ground of the relay module to one of the DB25 grounds? When I run my 445 nm 1400 mW laser module on the gantry, it has the power supply, laser, and DB25 grounds all tied together. Hopefully not permanently damaging anything on the left side of the opto-isolator by reverse-biasing that circuit path. IN1 voltage relative to the relay module ground is way out of whack. Should adding this line to the HAL file fix it?: So what's good? Externally supplied voltage level to the relay module seems good and DB25 pin 17 is at least doing something when the spindle changes state in LinuxCNC.Īnd the bad? I expected DB25 pin 17 to behave as an active low output, but it seems to be behaving as an active high. VCC relative to GND (both on relay module) = 5.06 V (still good what the USB charger is supplying to the relay module)ĭB25 pin 17 (output 1) relative to DB25 pin (GND) = 2.68 V (was expecting 0 V in active state) NO contacts of relay open NC contacts of relay closed IN1 (same as DB25 pin 17) relative to GND (both on relay module) = 10.54 V (bad IN1 should be within 0-5 VDC range)

VCC relative to GND (both on relay module) = 5.06 V (good what the USB charger is supplying to the relay module)ĭB25 pin 17 (output 1) relative to DB25 pin 18 (GND) = 19 mV (essentially zero was thinking it would be 3.3 or 5 VDC in inactive state) I fired up LinuxCNC with this configuration, homed the axes, and got the following results: I cover the how, and why, and will be offering a complete kit to make this a. Spindle section of HAL file is as shown in previous post (also included ini and hal files here - see attachments 3 and 4). This video covers the installation of relays in your G540 motion control system. This is normally used only for debugging or if both EEPROM configurations have been corrupted. P3 pinout is as follows: PIN FUNCTION 1 +5V TOP, SQUARE PAD 2 GND BOTTOM, ROUND PAD JTAG CONNECTOR PINOUT P4 is a JTAG programming connector. P3 is a 3.5MM plug-in screw terminal block.

DB25 pin 17 (G540 output 1) is connected to the IN1 terminal of the relay module (see "low" setting schematic of attachment 2). POWER CONNECTOR PINOUT P3 is the 7I92s power connector.

I hope.Got the relay module mounted and powered with an old Blackberry charger (5 VDC 0.75 A) that I removed the mini USB connector from and added color-coded leads to (see attachment 1). Gecko G540 + Ethernet SS looks great, but is pushing my budget! Probably really nice though.
#GECKO G540 PINOUT PLUS#
But when spending this much money, I’d just as soon ditch USB in favor of Ethernet, plus get the benefit of an external motion controller. There is a slightly less expensive alternative for using a notebook that converts paralled>USB. The Cooler plate sits below the G540 on its shorter standoffs, with the fan’s sticker side facing the bottom of the G540 The Control Card is pressed onto the top of the G540 and holds its self in place firmly. I would guess that you could (bad idea) control your mill or whatever remotely from your living room. The Gecko G540 and Cooler are mounted and separated using standoffs.

Here is their description of the SS:īeing an Ethernet device, it has its own IP address. They also have a USB model that is by their own description less capable that Ethernet SmoothStepper. The G540's current limit resistors require 1K per amp of motor current. The 1K + 2.2K resistor combination is the closest match I had on hand to 3K. I've got the test bench configured with a 35VDC power supply, four PK296B2A-SG3.6 motors, the G540 and cables with 3.2K resistors.

Īs I understand it, SmoothStepper is a high frequency motion controller that offloads work from the PC to the card, but more importantly in my case, it allows Ethernet connection to the PC rather than parallel port connectivity so you can use a notebook computer over Ethernet (or USB). The G540 drives four PK296B2A-SG3.6 motors very well. Works with the UCCNC software, Mach3 and Mach4. Then set the 'step duration' to 2 and 'Delay for Dir before Step' to 0. Note for the Gecko G540 controller - Choose setting for the MDLCNC interface. SmoothStepper is from Warp 9 Tech Design. Homann Designs UC400ETH - Ethernet Motion Controller UC400ETH - Works with UCCNC, Mach3 and Mach4 softwares Features: - Replaces 2 pieces of standard LPT ports. The pinout of J1, J2, J3 from top is: 2 4 6 8 10 12 14 1 3 5 7 9 11 13 Pin 1 is marked on the board. I can’t find SmoothStepper on the Automation Direct site.
