Hello Eugene!
I am an electronic enthusiast and planning to make the delta xr71 project,
but before proceeding to make my pcb, i am still checking first if the schematic circuit match to the pcb layout.
I noticed in the schematic ver. 6 of the delta xr71  that the ic 4538 vdd and vss terminals has no connection while in the one sided pcb they are connected, how will you account for this?

thanks and regards.

always refer to schematic while building the project, analyzed the schematic not the pcb. you can see connections in schematic then to pcb. always put in your mind that the circuit is analog positive ground. don't look for negative power supply, negative 12 volts in the circuit were used in mosfet source. negative 12v in the circuit have 2 rectifier diodes in series 1cap before feeding the circuit approx 11volts of negative supply. remember..the analog positive ground... not the digital ground of tlo62.

for best result of performance in dp, use all metal enclosure.

regards ram,

i build the DP but my unit only detects metal when it is very very close to the coil (23 turns, #24, 40 cm), problems encounter during initial test, first broken connection between VD8 to VD9, second is broken connection between P3 (20k) to R4 (5K6), TR2 frequency is set to 100Hz. I also changed the IRF740. Where could be the possible error? P1 (50k) and P2 (500k) are also ok with oscilloscope. Thanks in advance
