Hi Leslie and group.

I hope this schematic addition in the files section helps towards you resolving your current build issues.
For your interest I have in my current RELS " threading" section both Metric and Imperial screw cutting choices.
My lathe has metric leadscrews and all RELS menus work OK, I mention this as I read? you were concerned this mix of Metric/Imperial was maybe the cause of your non operative problems.
Through the last years I have added new tapers 1, 1.6, 2, 10,? 20,? 30.? 45, (MAX ANGLE)? degrees? and a vast selection of off the wall very fine thread pitches?needed
for my musical instrument repairs. The early Japanese musical instruments circa 1960?s that flooded the Western world countries and other household commodities using threads were?
not in conformity to the International Thread standards at that time. Now they use the ISO 965 which is the latest standards.
I believe the early Datsun circa 1960 -1975?s were a nightmare for finding replacement nuts bolts etc unless they were produced by Datsun. OE.

I have purposely not uploaded to the Files section my latest? V5 data or H files to include these additions.
These "add ons" can be easily?added on a "if needed basis" by the individual RELS users.

Cheers
John

I would like to clarify this point. What John says is completely accurate; you can mix metric and Imperial threading pitches. But you CANNOT mix metric and Imperial feed rates, As it states in the RELS_data_VX.XX.xls file, "Instruction" tab, row 24: "Only one Feed table is allowed in the TablesV4.h file!" The same is true for Version 5.

Hi John thank you and Charlie for help. It turns out that the keypad was configured with the onboard SMD resistors and wired for? analogue inputs? ?which Charlie suggested earlier. I scraped off the SMD resistors and wired each switch directly.
On another topic has anyone used the 12C? LCD in the sketch as it only needs 4 wires with a built in pot as well. I used the 12C LCD in a sketch on my mill feed but the sketch was preconfigured? by someone else. I had a dabble with trying experimentally to introduced the LCD 12c in an earlier RELS sketch but it came up with errors

Leslie,
Re your question, the I2C pins on the ATMega 2560 are pins 20 and 21. These are already used in the RELS to read the pulses from the encoder and are not available for communication with an I2C display. If the pins were available, the sketch would need to be changed to accommodate the different communications method.
