Just a thought, you are using a PCF8574 not a PCF8574A, because they have different addresses, this has cought me out before

With
#define UI_TEXT_BAUDRATE "Baudrate:%oc"
the baudrate is now displayed, but clicking on it puts a little star and locks you in that entry, a reset is needed to escape.
The steppers shake on moves, are they enabled and then disabled on every step? because that is what it feels like, im running a modified gen7 board and all the stepper enable pins are tied together.
thanks

another thing
homing and moving via the lcd system doesn't set the host's values, I assume this is because the firmware is unable to talk back to the host and is mainly designed as a standlone system.

thanks, option 1 seems to work well for the encoder.
It still freezes or resets on fast moves, slow moves seem to be OK , but slow moves on an axis seem to be trying to move the other axis as well, particularly noticeable is the extruder motor.
Also I lost all connection to the firmware, while playing in configuration/general the baudrate is not displayed, I clicked and twiddled, a * appeared a

Ive fitted a click encoder directly to pins 16 and 17, which works, but seems to jump 2 steps per click, I see in the code to swap REV for non REV and swap pins, but no matter what I do it seems to jump over the next menu item, I can get to the other items by turning the encoder half way between clicks. Am I doing something wrong.
Also using the positioning menu, and moving the head around somet

just put a 4x20 lcd on and the display positioning was corrupted, had to change
#define UI_LINE_OFFSETS {0,0x20,0x40,0x60} // 4x20
to
#define UI_LINE_OFFSETS {0,0x40,0x14,0x54} // 4x20
The line offsets are a bit strange, but this seems to be standard and its working well now

I haven't got my RW pin connected yet so I tried setting RW pin to -1 as suggested in the wiki, but it wont compile with ''DIO' was not declared in this scope.' leaving it set to a pin locks the firmware so it wont turn on, which is as I expected.
Also setting SIMULATE_FAN_PWM results in an error 'int fan_speed' redeclared as different kind of symbol.'
compiling with arduino 1.0

Its me again!
I've just changed my z endstop to an optical, leaving the x and y as mechanical. The optical is inverted compared to the mechanical, and the only setting is to invert all endstops. would it be an idea to be able to individually control each endstop, rather than all 3?
Its not a real problem as I've just wired the mechanical switches N/O, but normally a mechanical switch is wired N

Sorry to bring this up again, but been trying Slic3r 0.7 with the fan cooling, and I noticed that M106 S255 wasnt turning on the fan, I think with the code as it stands, it would enter the following routine with fan_speed = 4080 this is then compared to fan_pwm_pos which can never be 4080 as it rolls back to 0, therefore the PWM pin is never set high. Strangely if the fan was already running it

Try Repetier host, it's good! Remember that you need to click power on, in the manual control tab to turn the power on, after you have clicked connect, similar method to pronterface

I just tried with pronterface, connects etc as you describe, I think the problem is that pronterface isn't turning on the power supply. Manually sending a M80 turns it on and It all seems to work ok.

Just tried a print, doing strange things, I think it is missing commands while updating the LCD. I will wait for the expert to write the correct code.

Sorry, I've updated commands.cpp in the first post.( it was late ) I know you can do this a lot more elegantly than I can, I'm only just getting my head around this arduino stuff, spent ages just to get it to compile, couldn't find much information on using external libraries in other tabs etc. but I was just pleased I managed to get it to display something!
I have just tagged my code onto your

DO NOT USE - messes up prints!
i've been playing with your firmware, and have added a basic LCD temperature readout to my gen7 board, it is surely written badly, but it seems to work for me!

Ok, I will try to check that the wiring is ok, as the ambient temperature is very low at the moment so I will try and set the target temperature lower,
thanks again

Sorry, PSU is the power supply unit, in my case an underpowered ( since ive added the bed) ATX one which can't handle powering everything at the same time. I assume that turning off the bed in host should mean it is turned off throughout the print, since I don't think slic3r sets the temp. My problem is that it turns on during the print by itself, which trips the power and resets everything kill

I've added a heated bed this weekend, I warm it up at the start in the host, then turn it off before printing. Several times while printing and sometimes at rest at random intervals , the bed turns on, and since my psu isn't quite up to the job, it trips out, killing the job, also crashing the host. I have to shut down the host and restart.

The new release works perfectly now, thank you.
Im glad I have been a little help rather than just a user of your code.

The pwm period is about 6.8mS and the pwm granularity about 0.52mS, the period increasing by 0.52mS about every 7% of fan speed, this means that at after about 12 steps ( about 85%) it runs out of spce, but the code always sets the pin low on each interrupt period so that after 85% the period increases to allow for that low pulse. I think that in the first if/then sequence the fan_pwm_pos was ove

Sorry, hunting is when the motor is not at a static speed. The fan's speed oscillates above 85.5% going fast then slow with a period of about half a second and doesn't seem to really increase in speed above that point. It may be that the small MOSFET I've got cant handle the load of the fan, though I think it should.

Ok I will try that, it's my method of starting the machine that is the problem. I power it up home all axis then forget to raise z and send it to the dump area with normally some hard plastic sticking out of the nozzle. Just got to remember to raise z. After the print it works well.
I didn't realise that the EEPROM was unchanged during update.
Thanks

It works now! Thank you, but it seems to run fine up to 85.5% above that it starts hunting and not really increasing in speed. I will try and get a scope on it later to see if it is my drive mosfet.
Thanks again

These are not linked.
Is there a way to save the EEPROM data from within host and redownloading it when the firmware is updated?
Also I like the fact there is a dump area, which I use, but could the move be direct to the point in x,y and z, or the Order of movement changed so the nozzle raises up first. Since, as it is now after homing all axis the z is on the bed, and if you don't remember to l

I'm sorry to report that it doesn't seem to work. Tried it on pin14 and pin31 ( ic pin 20 and 40), no movement of the fan. Reinstalled the previous firmware (5b925be) and the fan turns off or fully on on pin 31.
tried with SIMULATE_FAN_PWM commented out and the fan works only on/off as expected.
It's below freezing in the garage so I don't really need a fan at the moment :-)

Wow, your fast, sorry but I've only just got in and can't try now, will test this out tomorrow night, and tell you how it goes.

Sure, if you write it, the least i could do would be to test it and report back.
