It only takes 5 minutes once you know what you are doing.I've been working on a small project, To make a remote DRO for MAch3 using Modbus. I spent more time than I should have figuring this all out. Also, don't forget to set the pulley 1 max and min speed under "Config->Spindle Pulleys."Ĭopy and paste the scripts from this post into your mach3 macros folder.
My spindle now runs M3 FWD, M4 Reverse, M5 stop, and speed control 80-6000 RPM with the variable drive pulley set at 3000 on the Bridgeport. The attached images have all of my settings. Set your base RPM and max RPM in the GS2 as well. Make sure to set you slave address in the GS2 and Modbus Serial setup to the same number. So for the GS2 you have only 3 options: 8-N-2, 8-E-1, or 8-O-1. The pin connections are as follows:Īlso, you need to set the communication protocol in the GS2, Mach3, and the COM port under windows device settings to be the same and they must be RTU. This isn't clear in the Automation Direct manual because it shows RXD going to TXD which would be a crossover cable. If you make your own RJ12 to DB9 connector you need to make a straight thru connection.
