Hi, Leslie,

The schematic I sent you, dated? 26-July-2020 in the file name, definitely corresponds to Version 5.

I know you have probably done this, but as I mentioned, the original keypad was designed for use with a single analog input. We found this to be unreliable in testing, and so changed to the digital design. However, if you wish to retain the original keypad and operate it digitally, it must be modified by the removal of all the internal resistors shown in the very original schematic fragment below. As the internal pull-ups are activated in the ATMega 2560, there is also no need for the +5 volt connection at all. If you have not removed these resistors, or if the +5 volts is still connected via the 2K resistor, this could be the problem.

I would suggest as a simple test that you disconnect the keypad entirely. Take a single, push-button switch and connect it between pins 25 and 27 on the 2560. After power up, pressing this key repeatedly should cause the display to shift from the Feed screen to the following screens in sequence. If it does, then the problem is the keypad. If it does not, then the problem is elsewhere.

Please let us know how you make out.

Hi Charlie thanks you so much for your help. Got the schematic and wired the keypad accordingly with pins 22? to 27. Still no joy, the LCD? shows the splash screen and then to feed but the keypad doesn't work.?
I am wondering if the? schematic is applicable for Version 5 ? Anyway I can revert to V2 and as said before works OK but I have to refigure the keypad back . Meanwhile best regards

Hi thank you very much

Leslie,

Schematic sent.

Hi, Leslie,

I will email you the latest schematic. Originally, I believe we used an analog input on the Mega 2560 and a keypad that, through a resistor network, would provide different voltages depending upon which key was pressed. We found that to be unreliable, however, and changed to separate digital inputs, as you will see in the schematic. I kept the original keyboard and rewired it as digital.?

Hi all, sorted the reason having issues with sketch and TablesV5.h because I copied the imperial feed as well from xls into Table 5.01.
Now the Keypad buttons will not work so reverted back to RELS 2.0 ino and the keypad works. Is there different Mega 2650 connection with Version 5.0 ino ? Has anyone got the schematic as seemed to misplaced mine

Hey all, picked this little guy up yesterday. Has anyone had any experience with factory made cnc mini-lathes? I can find the model number still made but it is a more modern full enclosed touch screen cnc machine

Thank you both for the kind words, but I am just trying to help out a fellow member and machinist.

Many thanks to Charlie for taking the time out clarifying and answering questions recently posted referencing the RELS? contained in the Files section.
He is a valuable group member,?
Well done.

Leslie,

I can't tell from what you've posted exactly where the problem is.

The first thing that I would check is the file name for the table. It should be "TablesV5.h" with no spaces. Make sure that the "T" in "Tables" and the "V" are both capitalized.

When you typed "# included" above, there was a space between the "#" sign and the word "included". This would generate an error if it is like that in your TablesV5.h file.

Another possibility is that you are missing a character from where you copied and pasted the green areas in the spreadsheet.

Yes, the number of pulses per spindle rotation MUST be 1800 for RELS version 5. I also had a 600 PPR encoder but I used a 3:1 drive ratio, resulting in 1800 pulses per spindle rotation.

I hope this helps.

Hi thanks for your help I have this error In the? ino file # included?

Hi, Ralph,

As you mentioned, the .h file must be in the same folder as the .ino sketch, as specified in row 32 of the "Instructions" tab of the spreadsheet.

I hope all is well with you...

Hi, Leslie,

As Ralph has pointed out, the "TablesV5.h" file must be in the same folder as the .ino file. If it is, opening the .ino file will pull the .h file in with it automatically, as long as the #include statement and the .h file names match.
