Hi ZPL I just updated to 109l but itappears to come up on the web 1.06 settings page as 109k ? Donby Don Recardo - Ormerod
I know the extruder wont run untill the temperature is high enough but there used to be a code to overide this Can some one remind me what the code is . I seem to have forgotten it ( its an age thing)by Don Recardo - Ormerod
Thanks for that David, Does ZPLs fork support your z Height sensor?by Don Recardo - Ormerod
I am using ZPLs web interface 1.06 and DC42s 1.09k it all works great except that when I am printing, the percentage done will get up to about 0.2% and then change back to 0% and also the filament used goes up far quicker than its actually being printed and then again will reset to 0 and start over again Everything else is working and the print comes out fine I dont know if its a problem wiby Don Recardo - Ormerod
Is it absolutely necessary to press the erase button every time I update the firmware ? The reason I ask is I want to mount a reset button outside the Duet case and that's easy to connect to the required signals I believe pin 4 on the expansion connector is reset and there are plenty of GNDs about but not so with the erase button , the only place I can see to take the erase signal from is the coby Don Recardo - Ormerod
I came across another filament supplier I gave them a try to see what their filament was like and have to report I was pleasantly surprised The only down side some may find with the filament is it comes in loose coils not on a reel but I didnt find that a problem They sell it in units of 100gms @ 2.70 euros ( about £1.95) per 100gms and you can buy as little or as much as you like if you orby Don Recardo - Ormerod
when I asked for my sample pack they told me if I want to order from them that filament is 19 Euro and delivery 12 euros for up to 31KG sent 48 hours trackable by DPD So buying more than one reel makes it better value Up till now I have been getting my filament from Etang Electronics They sell PLA £15.80 per KG free delivery ABS £13.80 per KG free delivery I am lucky because I live aboutby Don Recardo - Ormerod
Hi Doug Yes they just agreed to post me some , Its just that on their website it was asking me for 12 euros postage for the free sample which sounded a bit muchby Don Recardo - Ormerod
How much do you get in the sample pack ? I just looked on their site and it says delivery is 12 Euro which is rather a lot if the sample pack is not very bigby Don Recardo - Ormerod
Thanks Dave I will give it a go Donby Don Recardo - Controllers
Is it possible to use optical end stops on a Duet control board and if so what will I need to change in config.g and how should I connect them up? I have some Honeywell H0A1887-12 which I know I will have to add a resistor for the LED current limit but will I need to put a pull up/down resistor on the output, and which pins do I use on the duet Donby Don Recardo - Controllers
Its Ok I have it sorted It uses the same one as the white pcb display is showing up fine nowby Don Recardo - RAMPS Electronics
Trying to get my 128X64 LCD working in marlin but cant see the right option to choose The display PCB says its a RepRapDiscount Full Graphic Smart Controller In Marlin config.h I can see several LCDs to choose from . the nearest to mine seems to be The RepRapDiscount FULL GRAPHIC Smart Controller (quadratic white PCB ) but mine has a red PCB , maybe an earlier edition ? which is the rigby Don Recardo - RAMPS Electronics
You don't even need to measure the resistance to tell which two wires come from the same coil just hold any pair of wires together and try turning the motor if it turns easy the two wires are from different coils if its real hard to turn they are from the same coil Donby Don Recardo - RAMPS Electronics
Thanks for the reply Dave I for one would be happy to fit the through hole parts to save a bit more money I shall follow this thread with interest Donby Don Recardo - Controllers
Quotedc42 The parts cost is less than £15 including PCB. Assembling it in the UK would be uneconomic because of the large number of through-hole parts (i.e. the connectors), so it would have to be assembled in China. I'll get some quotations when the Chinese New Year is over. The initial selling price I had in mind was about £35, but if the production volume became high enough then sub-£30 + shby Don Recardo - Controllers
Thanks for your help I had began to think I was going mad but its making sense now Donby Don Recardo - RAMPS Electronics
Quoteenif The analog pins on the Mega A0-A15 are internally represented by the arduino pin numbers 54 to 69. These plain numbers can also be used when referring to those pins as digital pins. Thus, arduino pin 54 is actually the same as A0, which in turn corresponds to the physical pin 97. Thanks for the reply Do you know of a table anywhere that shows the correlation between arduino pin numbby Don Recardo - RAMPS Electronics
Hi I am still waiting for my Ramps 1.4 board to arrive from China but trying to get to grips with ramps while I am waiting I looked at the PCB for the ramps board in Eagle and the step pin on the X axis driver seems to connect to the arduino Mega 2560s Analog zero pin which according to the arduino pin mapping sheet is pin 97 Now according to Pins.h the X step pin is defined as pin 54 notby Don Recardo - RAMPS Electronics
The most likely reason they get hot is an imperfect connection between the wire and connector the same reason why they have trouble with the heater terminals on Ormerod 2 heatbeds, the nuts on the connector posts work loose . you get resistance between the wire and post and heat is the result Why not just solder the wires on to the board . That will more likely be a good cure to your problem anby Don Recardo - RAMPS Electronics
I quite agree about there will be extra weight but I was not thinking of doing it on my Ormerod but on the big printer I plan to build . that will have a z axis at each end of the X axis for support and all three axes will use linear guides like this The guide rails are 40mm wide by 760mm long . I know a company that uses these to swing something back and forth at over a meter a second . Theby Don Recardo - Ormerod
I had thought of M5 thread but worried that the thread being even finer than the M6 might strip with the force of the extruder , and for some reason the M6 were a little cheaper too I would love to try an extruder that doesnt use a bowden tube , The extruder motor and hot end are joined together as one unit (I dont know what they call that type ) . I wonder if anyone has tried one on an Ormerodby Don Recardo - Ormerod
I found a nice neat little 4mm pneumatic fitting that has a 6mm thread so doesnt need too big a hole to fit it It was Ebay item 271290823788 , They only cost me £4.44 for 5 fittings I altered the normal extruder body to be able to take the fitting after you have tapped it 6mm I also thickened up the body of the extruder on the inside of the curve between where the filament enters and leaveby Don Recardo - Ormerod
Hi cdru thanks for the reply It looks like you were right . I put the output of the arduino on my scope and it is putting out a rising pulse so I will have to invert that before feeding it to my steppers I take your point about achieving a high enough step rate with the Mega , but it had never been my intention to run the microsteps at 128 or even 64 , I was just saying that is what the driverby Don Recardo - RAMPS Electronics
Thanks George , that's the enable pin sorted, do you know if there is a similar command for the step inputs ? Direction input is not a worry, I can simply reverse one phase on the stepper to change the direction the other way Don Quotegeorge4657 You can set enable either way in config file // For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1 #define X_ENABby Don Recardo - RAMPS Electronics
Hi I am thinking of making another printer, muuch larger with bigger steppers I plan on using a Ramps 1.4 board which I have just placed an order for I already own some nice stepper drivers (MSD415s microsteps to 1/64 and MSD542s microsteps to 1/128 ) and my plan was to make some small plug in boards that will go where the plug in driver normally sits on the ramps and this will allow me toby Don Recardo - RAMPS Electronics
Quotedc42 Three stepper motors in a triangle. Think of the 3-point bed mounting of an Ormerod 2, or an Ormerod 1 with DaveK's bed support upgrade, with a stepper motor driving the screw at each mounting point. Except that the stepper motors also serve to raise and lower the whole bed. For a really large printer, the bed might not be stiff enough to prevent twisting by a significant amount, andby Don Recardo - Ormerod
Quotedc42 If I were building a large format printer, I would be tempted to use three Z stepper motors, driven independently by the electronics. Then the firmware could use the Z probe to do 3-point bed levelling by driving the motors independently, as opposed to the bed compensation that we use on the Ormerod. Of course, this would require firmware changes. I cant visualise how that would workby Don Recardo - Ormerod
