Re: Nema 17 Stepper Motor Noise - 8 years ago

Sorry to make you confused.MKS SBASE is compatible with Smoothieware that supports 1/16 and 1/32 .But MKS BASE is MEGA2560,use 4982stepper drivers which only supports 1/16.

to Chri: i have reply you, thank you. to karabas : to w3drk : we change uC oscillator because it will be better for the lan, and not relate to lockup issues. the lockup issues maybe come from sd card problem. we have found MKS Sbase need better sd card then Mega2560's board. I have send SCH and PCB and BOM file of MKS SBase V1.2 on to Github, they can be find here: https://github.com/ma

thanks w3drk and other friends, we have change the Crystal,replace CSTCE25M0V53-R0 with QRA26B25.0000MFT2C2F, replace CSTCE12M0V53-R0 with QRA26B12.0000MFT2C2F to fix the Ethernet bug, now we change it by manual and will fix the problem on next version. We don't find the bug because we print some small file by lan and it is ok in our Lan. But use CSTCE25M0V53-R0 is our fault,it will cause unst

V1.1 no need do anything, it is ok. LG1 is a magnetic bead. The base function of LG1 is connecting AGND (motor) and DGND (CPU), we add it to reduce disturbing from motor to CPU. In normal voltage between AGND and DGND is 0, but short circuit or other accident maybe cause LG1 over-current( max current is 2A) and burn. We delete it because we found LG1 is not very useful. But reserve it is n

Re: New MKS SBASE Smoothieware-compatible board from China - 9 years ago

v1.1 and v1.2 is very small different, we delete LG1 because it is easy be burn when accident. when we change pcb,will change version. So we change it to v1.2.

1. take off component D5 and F3; 2. Connect R-78E-5.0's 3 pins to the 3 solder joints as shown in the picture, (pin1 to label 1, pin2 to label 2, pin3 to label 3),then it can work well.

I have delete doc copy from smoothie web, and add MKS SBASEV1.1' PCB and SCH file in pdf .Github This is not enough, and can't be identified as Open-Hardware. Becase of we don't like see it be clone with bad component after a month, and we are accused by purchaser(this things

Re: New MKS SBASE Smoothieware-compatible board from China - 9 years ago

Quotearthurwolf Quoterocketwiz Also what's with the heatsinks on the 8825's? Shouldn't they be on the (possibly too small) solder vias on the other side? Yes, putting the heatsinks on the top is definitely very bad design, from somebody with no experience in this, who has not even cared to read the datasheet for the drivers ( or understands how they work ). This is the same attitude that caused

hi, MKS SBASEV1.1 have for sale. respect to MKS SBaseV1.0 : 1. fix Temperature problem. 2.add Thermocouple Pins( can't be used with 12864lcd together). 3.add some pins P1.22 P1.23 P2.12 P2.11 P4.28 for customization use. 4.add endstop power select function,can select 3.3V or 5V

Re: Part blew up on Prusa i3 motherboard MKS Gen-2Z v1.1 - 9 years ago

1. LG1 is a magnetic bead. The base function of LG1 is connecti ng AGND (motor) and DGND (CPU), which can reduce disturbing from motor to CPU. 2.These reasons can cause the burning of LG1(may be more reason): 1) Voltage between AGND and DGND is too high. High voltage will cause LG1 over-current( MAX current is 2A), and the other parts of MKS GEN may be damaged or not. The high Volt

Re: New MKS SBASE Smoothieware-compatible board from China - 9 years ago

innkeeper , frodriguez96 : change the DC-DC from L5970D to R-78E-5.0 can solve this problem on V1.0. arthurwolf : yes, DRV8825 and A4988 's radiating is on the chip bottom, so the best method to cool them is by the PCB, so we have carefuly deal with it on our PCB. But if the current up to 1.5a or higher, the temperature is also too high in spite of good PCB design. So add heatsink is

Re: New MKS SBASE Smoothieware-compatible board from China - 9 years ago

thanks frodriguez96 , lmclaren: we have found the reason of temperature problem come from DC-DC, L5970D 's Switching Frequency is not enough , we are testing new DC-DC now . This problem will be solve on on MKS SBASE V1.1 , and will add pins used for Max31855 thermocouples ,add heatsinks on Drv8825, just as frodriguez96 said. . MKS SBASE V1.1 will be saled about August or Setpember.

to arthurwolf ,CapnBry : We have reseach the problem for some day. you are right,this problem is not about firmware. The most possibility come from voltage Interference. we will change the DC-DC and pay attention to analog ground and test if can solve this problem. Our board Circuit diagram can be found at here

To CapnBry , Thanks for your trying our MKS SBASE Smoothieware-compatible board and find the problem in maintaining hotend temperature.After we compare the origenal Smoothieware oard and our MKS Sbase. We find that when we use the DC-DC converter R-78E5.0-1.0 as origenal Smoothieware, it is OK. And our DC-DC conver L5970D is using in our MKS series Board for 2 years with Marlin and other f
