Re: Better, finite-jerk acceleration? - 8 years ago
Given the speed capabilities you describe, you should actually be able to reduce jerk a little and increase your accels for less noise smoother motion? You clearly have some experience and know your way around so I am only making the comment. I am not quite sure I follow your finite/infinite jerk description though. Jerk is an instantaeous direction change. Are you suggesting a jerk/junction deviby Mutley3D - General

Re: Only the extruder needs to be accurate - 8 years ago
Vibration is only part of the problem, and the majority of well built machines are stiff enough to not have such vibration. Flex shaft extruders can help on cube style machines and deltas, where flying extruders are also an option. The amount of weight in these arragements is not enough on its own to cause the acceleration ringing. It is fine acceleration mismatches and actual integrity of steppeby Mutley3D - General

Re: New print surface material? - 8 years ago
@Animoose - That difference between 80c and 85c I think you have demonstrated very well that it can be a matter of just a few degrees to switch that adhesion on. Glad to hear you got a win there. @hobbymods - Looking very nice there indeed.

Re: TMC 2100 and ramps - any pitfalls to avoid? - 8 years ago
Quotedrmaestro QuoteMutley3D Most of the drivers commonly used in 3D printing, are designed for general stepper motor control (Pololu etc) and not specifically 3D printing which requires steppers with absolute motion control integrity. ie no micro-step jumping for best results. J Does that mean we still don't have the ideal stepper drivers yet? Ideal would be servo based, but would it be practby Mutley3D - General
Re: TMC 2100 and ramps - any pitfalls to avoid? - 8 years ago
Depending on the version of TMC2100 (clone/Waterott/other), beware there are slightly different configs. Some clones also have CFG1/2/3 labelled incorrectly, same but different. Principally two modes of operation. Stealthchop and Spreadcycle. Pro's and cons with both. There are even deeper config options available with both modes, based on very small soldered jumpers on the underside. They willby Mutley3D - General

Hi Richard, Yup I let you down, delays over-running. It happens. Genuinely sorry about that. My delays are my own fault and some way beyond even my own comfort zone. I hold my hand up.

Flex3Drive Cyclops Program - OFFICIAL - 8 years ago
A quick update on the Flex3Drive Cyclops pre-release program. We have been running slightly behind schedule (as always seems to be the case in 3D tech). This does not mean we have not been working behind the scenes. Things are now starting to move and and the first assemblies are heading out this week and the rest early next week. My apologies on the delays. More info and details will be postedby Mutley3D - General
Re: New print surface material? - 8 years ago
Quoteanimoose Has anyone had luck with nGen on PrintBite? I haven't found settings that work well. It does stick, but not very firmly, and so print sometimes end up peeling away from the print bed after a while. I am using 220C on a bed at 80C, but have varied both values up and down from this. You absolutely need to be running hotter on the nozzle. 220c is too low. Probably need to increase bedby Mutley3D - General
Re: Spaghettification half way through print - 8 years ago
Symptoms described above suggest momentary thermal shutdown on the stepper driver, having reached a critical temperature after a given amount of running, hence occuring roughly around the same point in the print. Have you got a fan cooling your electronics? (ill hazard a guess that you havent). If not, put one on, and also make sure you have heatsinks on the stepper driver chip. That should remedby Mutley3D - General
Re: Auto bed levelling - IR, inductive or nozzle probing - 8 years ago
@slanwar - you dont need to run M502 before printing or typing code. M502 simply loads the values that are hard coded - ie the values in the code when it was compiled. When you have made changes to settings using M commands like M201 M204 M205 etc, you store these settings into eeprom using M500 command. If you then use the M502 command you are effectively resetting the values you modified backby Mutley3D - General

Re: I Wish to Upgrade my Print Bed - 8 years ago
Remove the relay circuit and run directly through the MOSFET on the RAMPS board for the heated bed and use PID - Try this first, but also put a small fan onto the RAMPs to keep it cool if not already doing so. If the reasons for your banding are releated to use of "bang bang" control on the bed heater, using PID will resolve this.by Mutley3D - General
Re: New print surface material? - 8 years ago
@stephi - I have not tried ESUN PC so I cant comment on this particular brand. I do however print Polymaker PC with no issues on a bed @120 with nozzle @ 275/280 I suspect that your bed temp of 140+ is possibly too high so drop this to 120 and try again. Please also note that since ESUN is a budget brand it may not adhere aswell as others, however as per dtwrv6 suggests, you could try applyingby Mutley3D - General
Re: Please help with Y axis rounding values steps/mm - 8 years ago
QuoteFloyd Quotedc42 so your issue is likely to be that the Y pulley has a different number of teeth from the X pulley. That would really only matter to the motion. If he has it set as 80 steps in the firmware then the display shouldnt be rounding like it is. Two different problems occuring - one is a computed accuracy rounding of 0.1mm in every 4 to 5mm moved, the other problem is a measured moby Mutley3D - General
Re: Please help with Y axis rounding values steps/mm - 8 years ago
Start at the beginning - count the teeth on both the X and y axis pulleys. I have seen 16 and 20 tooth pulleys mixed up. Most likely (not) your issue, but check to eliminate the possibility. Edit: (place your bets!) - just looked closely at the two images showing each pulley, unless there is a trick of the light, the Y axis pulley does look slightly larger - the outside of the belt looks closerby Mutley3D - General

Re: Anyone know the correct name for these? - 8 years ago
@Rlewislou666 - these are angle brackets as mentioned, the item you show is a 10x10, KJN in the UK also have 20x20 which may fair stronger for you but are extrusion dependant (ie slot width) however the locating tabs on these can be broken off. What extrusions do you have currently? If they are Bosch-Rexroth compatible extrusions then KJN items will be fine. You will also require t-nuts - KJN aby Mutley3D - General

Re: Flexidrive is Flex3Drive Early Birds - 8 years ago
Slanwar, the Prometheus utilisies the same groovemount spec as the JHead, so just select JHead option and put a note in with the order that you have a Prometheus, and the correct cooling fan shroud will be supplied, as this differs for different hotends. However it does appear you wont need to use the fan shroud if using the Prometheus spec fan. For prints of extended printing time one must haveby Mutley3D - General
