My Heiz controller box stopped working the other day & thanks to this thread & google I managed to fix it. Those diodes are there on the + output of the bridge rectifier on my box even though they are not on the circuit diagram. One had become disconnected from the connection to the circuit board due to a bad solder joint. Resoldered & all is good :-)

Before the controller failed I thought the cooling fan was dying as the speed of the fan was not cosistent, I guess this was due to unsteady voltage from the failing solder joint.

General Mach Discussion / Double entries with 3d Probing Plugin

« on: May 17, 2008, 01:28:48 PM »

Hi,

 I have been trying out the 3d probing plug in with the demo version of Mach3. The probing routine seems to work fine but when I look at the resulting .txt file there are two entries for each X,Y position. The only difference between the two entries is the Z axis reading which differs by .05mm exactly what I put in as the probe clearance in the 3d probing dialogue  ie:

11.50062,4.50000,-0.55875
11.60062,4.50000,-0.50875
11.60062,4.50000,-0.56000
11.60062,4.53937,-0.51000
11.60062,4.53937,-0.56062
11.50062,4.53937,-0.51063
11.50062,4.53937,-0.56187
11.40062,4.53937,-0.51187
11.40062,4.53937,-0.56250
11.40062,4.50000,-0.51250
 
I have slowed the feed rate down to 15cm per minute to avoid probe bounce. Everything is set up correctly (as far as I can tell) in the ports & pins config. The probe only shows one hit per contact on the diagnostics screen in Mach3     Any ideas ?
