Re: Maybe Belt/Motor Skipping?
I am trying GeraldO's fork from this thread
http://forum.seemecnc.com/viewtopic.php ... ldo#p28703" onclick="window.open(this.href);return false;
It has Horizontal Radius and is the latest version.
So I now have repetier 0.91 on the ramps I think...
I'm not sure I'm qualified to be the first user / tester though
as I don't have a comparable experience of functioning firmware.
I may be hard to tell what's broken and what's working.
I am finding different versions of Repetier firmware reverse the polarity of all my motors.
Is it safe to just flip the cables round to fix this or is that a no-no?

Re: Maybe Belt/Motor Skipping?
Strange - the Hot end still won't get hotter than 205-ish degrees now I am on Repetier..

Re: Maybe Belt/Motor Skipping?
Just based on what I see from the EEPROM screenshot, you're not using .91 - there's a TON of stuff in the .91 EEPROM table.
Instead of flipping the wires in your stepper motors, you can just reverse them in the firmware. I don't recall the exact name of the fields, but you're looking for "invert" with regard to the X, Y and Z axes. (rummages around in Red Sonja's firmware directory)
Ok, look for this block:
Flip those to the opposite of what they are now if your motors are going in the wrong direction. Saves wear & tear on the connectors & pins.
I'm wondering if it would be beneficial to have a "group hangout" with myself and some others to see if we can't get this machine behaving. We'd need at least one person with RAMPS experience.

The RAMPS board does not have locking connectors so you can simply turn the connector to reverse direction.

Re: Maybe Belt/Motor Skipping?
Hi GeneB,
Don't worry, I am using 0.91 now, the screenshot was from one of my earlier attempts yesterday.
I have since upgraded to a functioning version of 0.91 and the only problem is temperature stuck at 205.
Yes, It would be great to find someone who has used a Rostock Max with Ramps.
I am available for a group hangout if anyone like that is around.
Board member GeraldO is using a Rostock Max with Ramps and Repetier, but he is still assembling his kit:
http://forum.seemecnc.com/viewtopic.php ... ldo#p28703" onclick="window.open(this.href);return false;
Delta Radius sorted. Motors Sorted. Main problem is the temperature now.

Re: Maybe Belt/Motor Skipping?
Have you done the PID tuning for the hot-end from Gene's manual? I'm wondering if the default values (assuming you haven't already done it) are just off.analog_banana wrote:Hi GeneB,

Re: Maybe Belt/Motor Skipping?
I have done the PID tuning many, many, times!
I guess the tables are different or something - I'll do it again
Currently I am just putting in the figures from last time I tested in Marlin.
I am pretty sure I have the same, normal Thermistor and heater as everyone else.
I think I have them set correctly in Repetier?
My Hardware:
100k Thermistor:

6.8 Ohm Heating Resistor
http://seemecnc.com/products/6-8-ohm-heating-resistor" onclick="window.open(this.href);return false;
In Repetier I have set these values:
// 1 is 100k thermistor (Epcos B57560G0107F000 - RepRap-Fab.org and many other)
#define EXT0_TEMPSENSOR_TYPE 1
//1 = PID Temperature control.
#define EXT0_HEAT_MANAGER 1
/** \brief The maximum value, I-gain can contribute to the output.
#define EXT0_PID_INTEGRAL_DRIVE_MAX 240 ****I changed this from 205

Re: Maybe Belt/Motor Skipping?
If you re-load the Marlin firmware on the board, does the hot end come up to temperature properly?

Re: Maybe Belt/Motor Skipping?
I can't PID tune the machine in Repetier at the moment,
I get the following error:
Error:PID Autotune failed! timeout
I will try going back to Marlin to check the hotend...

Re: Maybe Belt/Motor Skipping?
Check these values in the EEPROM:
These are the stock values from the firmware I'm using in Red Sonja (the only firmware directory I can reach right now).
The P, I and D values are different in my EEPROM however - I did the PID tune, but it'll get you close.
Make sure EXT0_PID_MAX is at 255.
g.
Code: Select all
#define EXT0_PID_INTEGRAL_DRIVE_MIN 60
/** P-gain. Overridden if EEPROM activated. */
#define EXT0_PID_P 31.36
/** I-gain. Overridden if EEPROM activated.
*/
#define EXT0_PID_I 2.18
/** Dgain. Overridden if EEPROM activated.*/
#define EXT0_PID_D 112.90
// maximum time the heater is can be switched on. Max = 255. Overridden if EEPROM activated.
#define EXT0_PID_MAX 255

Re: Maybe Belt/Motor Skipping?
Thankyou!!
that's got it working!
I have set:
Pid drive max = 205
Pid drive min = 60
(these were the defaults)
I'm doing another pid tune then it's time for a print

Re: Maybe Belt/Motor Skipping?
Corners look slightly better, but the raised, blobby corner issue is still there.
The nozzle grates over the raised blobs of corners or tight curves.
this compounds into artefacts that spread upwards into the print.
Thanks to everyone for help getting Repetier firmware running!
So what of these Jerk settings?
I can find documatation for repetier host, but not much documentation for the firmware...

Those cubes were 5mm per second as before. I'm working on site with a client, so I can't hang out today. I'll probably do some spread tests of temperature, then maybe test the enigmatic jerk settings

This is a vast improvement.
For a successful print I find that the print cooling fan MUST be on...
Without it I get the usual mush.
It's interesting to see that the "official" Orion ABS settings use a print cooling fan.
I have been told many times to never use a print cooling fan for ABS - but it still seems to be essential to me.
And maybe it is OK if SeemeCNC are issuing settings that use a cooling fan for ABS?
Thanks again to everyone. I'm seeing progress..
